Motorola SBG6580 Customer Reviews
Be aware when connecting to Cox in AZ...
I'm not certain if these modems are working properly in Arizona right now for Cox subscribers. I replaced my old modem with this model. It would connect very nicely, and was easy to set up for wireless, but 30 mins later it would lose its connection with the DNS servers at Cox. The modem itself said it was connected to the internet, however, since it could not connect to the DNS server, it was not able to surf the web via name. The Cox technician was very good, and replaced cabling at the house, and we even replaced with a similar model, same issue. I went with the Motorola Surfboard modem (not Extreme)..with DOCSIS 2.0...and it worked right away. So, until Cox irons out issue with this modem, please be aware you may have some issues....

Great all around Modem/Router gateway
I bought the Motorola SBG6580 about a year ago. I got it to replace the Comcast modem and Belkin router. It was a no brainer. Once i had it hooked up and out of the box i called comcast to give them the number they needed to send my signal to and it has been running flawlessly since. It works well in every room in my house including out on the patio. There were a few times where I lost signal but that was due to my connection to Comcast. I am running 7 wireless devices and 1 hard wired device and not a drop in speed. I would highly recommend the SBG6580 to anyone for either home or business use.

Not worth the money
I have had this device for more than a year now, I had to reboot the device every week or so, I was ok with it until last week. I had to reboot the device 5 times a day. I called comcast and they finally send someone over, after hours of troubleshooting checking signals here and there and testing other modems, the tech concluded that the device was faulty. He even pointed out that he is only getting 2MBPS over the wifi and over 20MBPS when connecting directly to the device. unfortunately the warranty ran out last month! :( I have had other modems for years without any problems the reason I switch to this one was to have both the modem and wifi in the same device. I wish I had read the posts before I bought this piece of junk! Motorola should be ashamed of themselves.

Solid Modem/Wireless Router.. When it stays online
I have no issues with this Modem/Wireless Router combination other than the fact that the modem goes offline a few times a week and requires a power off & power on to restore connectivity. My previous modem/router combo had less power on/power off cycles in 5 years than this unit has in one month.

Great when it worked
Decided that $7 a month for a modem made no sense when I could buy my own. Under the advice of the Comcast rep at the store I purchased this all in one wireless juggernaut, his words not mine. After calling Comcast to have them record my MAC ID, I setup my modem/router (very straight forward) after about 2 hours of use the problems began. I constantly lost the signal to all of my wireless devices, causing me to enter the password multiple times even though I did nothing different to my initial setup. After about a week of this, a few Comcast technician visits and me wasting time constantly re-entering passwords, I returned this device and got the traditional router & modem (DOCSIS 2.0) that I had previously.

Poor quality modem
I have returned 2 of these modems due to their inability to keep running. I have never had a problem with any other modem I have run. It is nice that it has wireless connectivity when it works. However it hardly worked and the speeds were slow. It also took an extended period of time to recognize the computers when they tried to reconnect to the internet. It is just a horrible modem.
Review by Simba30 ().
if i had 2 more thumbs ill give it 4 thumbs down,
(i have comcast) the main problem is the combo concept it work great as a modem only but the router part of it is top of line garbage. if there is any issue with this product that you will have its router related. the device needs to be taken off shelves and recalled. I asked the clerk at the returned counter about this item. she laughed and said this item has the highest return rate and that people always complain about the wifi connetion....FYI.. the setup was also hard to figure out and the wireless went out in the first hour... took it back and got the $99 surf board extreme cable modem and the $90 netgear n600 dual band router. unlike DSL, i guess cable modems are not yet ready to be built in to an all in one device, BUY SEPARATE
Review by Veye ().
The equipment that I was renting from my internet provider was unreliable. I was losing the signal everyday. The company that I am with was very helpful, but the problem could not be resolved. I even received a discount due to the faulty equipment. After four technicians and two rented modems/routers later, I decided to purchase the motorola surfboard 6580. I am glad I made the purchase. So far the 6580 has been very reliable. The wifi is stable and fast. I have read some reviews that stated people were having issues with the unit. I may have lost connection one time for about one minute, but no other problems have happened. Before anyone makes this purchase, make sure your internet provider is capable of handling the docsis 3.0 cable modem. Also I was told to disable the ip flood feature in the firewalls tab when setting up the modem to help increase the speed and function of the motorola 6580. Hope this helps!

Very good modem, does get warm, but all my other stuff gets hot too, so I don't care.. It's not overheating, just slight warmth to the touch. I have a Netgear N600 Dual Band from BB. I have no dropped connection issues. All my major stuff is wired to the Netgear. I also have a rocketfish Powerline adapter, solid signal transmission all the time. I got this modem for FREE from my ISP, I couldn't imagine paying upfront for another modem after buying a worthless Clear4g home and laptop modem. I get a solid 22 Mbps, I only pay for 20 Mbps... I like this modem a lot. Too easy to setup, just screw in the cable before powering up.. It found internet signal in 10 seconds.. I didn't want the wifi, so TWC turned that ability off. I don't mind.. I have a very busy network, I gotta have something like this modem to meet my demands. Clear4g didn't meet my requirements. Get this thing, you won't regret it. Most ISP's give this unit away.. Obviously if you get rid of the service you return it, but I don't wanna own them anymore. I'm more interested in keeping my own Router, that thing cost a lot.

High hopes, sortof delivered...
My router died so I bought this all-in-one Modem-Gateway unit to replace both the router and the modem I was renting from the cable company. IF you use WPS security, IF you have a small area for the wireless to broadcast, and IF this unit will be in a cool location, then this might be the right hardware for you. It is easy to set up as long as you use WPS security, but it does seem to run warm. Also, my across-the-street neighbors' network broadcasts stronger than this router. finally, I have an old computer with a WEP-security wireless card that I have to maintain on my network. This unit wouldn't allow me to run WEP on the network unless I turned off Wireless N (bummer, since I paid extra for that). Also, I couldn't even run WEP on the same network - I had to set up a separate guest network to run WEP. The main network ran WSP security and was really easy to set up, while the second network was more difficult although the same hardware ran both networks. Too bad that i can't access the network printer from both networks though. If you are running all the current security, etc, then this might work but if you need to run anything out of date then you should pick something else. This becomes a nightmare trying to make it backwards compatible.

Constantly drops connection now
This modem has frustrated me so much, I had to write my first review - ever. Bought this modem about 4 months ago. It lasted 3 days before it started dropping my Internet connection with Cox Premium. I replaced it and got the extended warranty just in case. About 3 weeks ago, it started constantly dropping the connection requiring a modem reboot (unplug/plug). I have been rebooting about 10-15 times a day if I use it all day. After a week, called Cox. They suggested getting separate modem/router. After two more weeks, I called Cox again. They insisted they had no record of dropped connections for over 100 days and that the model is 100% compatible. Again, their solution was to refresh my signal and for me to reboot. It did nothing of course. So I have to assume this is a modem issue and return it - not knowing for sure what the real issue is. With the extended warranty, I am going back to Best Buy one more time to replace it. Bottom line: Motorola cannot update any firmware. They say the provider has to do it. Cox says it is fully compatible and has no interest in a firmware update. Could it be a bad chip? It runs warm - is this a problem? Who knows what the real reason might be. Personally, I think it is one of those situations where the early versions were either defective or are no longer compatible with Cox equipment, but no one wants to admit it. This is where the consumer carries the burden with few options other than to replace the modem. It's too bad because I like the modem. It was fairly easy to set up, especially if you have Windows 7. Speed was good with DOCSIS 3.0 Cox Premium - and it easily handles all my wireless devices. It's a shame I cannot recommend it.

This has poor signal around the house. The wireless is nearly worthless. Will not stay connected. Gonna contact Charter to determine if they are the problem!

The reviews don't lie
I was really hoping this would work out for me and that past reviewers were just having trouble and clueless as to how to make it work for them. Here's my verdict: the product should work for you, not the other way around for the average consumer. This fails. I'm not a tech wiz or someone that claims he knows everything, but I am also fairly knowledgable and self-reliant in troubleshooting and solving my own problems. With this product I ended up getting frustrated in setting it up and making it for and stay working. I have Comcast and it was in the list of compatible modems. Called to activate it with no problem and it worked fine with my Mac mini that is connected through the ethernet cable. Worked fine for the first 10 minutes and did a speed test to see what I was getting, 19Mbps when my plan I pay for is up to 15Mbps that impressed me. But once I got my Laptop Macbook Pro connected via WiFi it worked for a minute or two then the webpages on any and all browsers would load really slowly or not at all. Same thing happened to the Mac mini even though it was connected with a cable. Called Comcast and they tried helping with no success, called Motorola's 800 number and the rep ended up telling me he found nothing wrong with it on his end and that he recommend I just return it as it may be a defective one. I guess a lot of people are getting defective units. Before returning it I decided to go online (through tethering on my phone) and seek help, tried everything from clearing out the cache, resetting all browsers by clearing out all data, removing preference settings on my mac and also modifying setting on the modem itself. Which of course didn't help. In the end I returned it and got the Zoom 5350 Wireless Cable modem which was an easy set up and activation as well but I have not had any issues with my internet, WiFi, slow down in speed or connectivity at all.

Did NOT Meet My Expectations
Purchased this item July 13, 2011, and have had problems since. I went from the SB5101 & Belkin N Wireless Router and had no problems at all. I purchased the SBG6580 to get rid of clutter, and of course to take advantage of the 3.0 techonology. Cox and Motorola keep passing the buck having me change some settings, but none of this has worked. My issue is the WiFi. My Laptop and two Samsung Infuse 4G's all reconnected to my WiFi within range of my equipment automatically as they should everytime. Now, I literally have to click as many as five to eight times when using my Laptop to get to the website I want to visit. My Samsungs, I have to toggle my WiFi off, then on, and they will connect to my equipment. As I said, this was never an issue until I switched to the SGB6580. It will be returned TODAY! MOTOROLA, you have never disappointed me until now!

Gets rid of clutter
The modem is a plug and play, which I like. The instructions were very poor. I had troubles getting the wep number for the wireless. After going to Motorola's web sit, the instructions were there. I did as it showed and now the wireless works great. I'm not sorry I purchased this modem.

It is a great Wireless Gateway
The cable modem gateway is a good producti. However, the instructions for installation was lousy. The tech writers definitely need more work. After connecting the wireless gateway to the first computer using the installation disk, the gateway gave me a password to record. I was supposed to use that password to connect other devices. This was not correct. The password did not work. To connect devices with Android, Linux, and Windows 7, I had to use the key as the password to get a connection. Once I figured this out, then these devices were easy to connect. Then I used the gateway to restrict access to only my devices by using the devices MAC addresses. Now, everything works beautifully!

Very unreliable modem
I got this modem though BBY store - an associate recommended it because it is all in one. This seemed like a great idea at the time but it has been an absolute headache bordering on useless. Poor signal, constantly drops connections etc. I've changed that channel and done what I can but still does not work reliably. I cannot get signal in my basement where I used to get it with a wireless g before. Do not purchase.
Review by Parl ().
I've had this modem for over a year now with bright house networks as my ISP. I could go on forever about the tech information and the connection this modem provides but instead I'll simply say this. For the time I've had this modem, I never had a problem with the device itself. The one time I did have a connection issue, the problem was the CMTS itself. (Which is what is on the other end of the cable line feeding you innernets.) It has great a great receiver/transmitter works flawlessly if you have a good connection with no major loss in the line.
Review by BansheeHsky ().
This modem worked for approximately 5 minutes. I installed it, had it registered with Cox Communications, they said there was a very strong signal going to the device so I shouldn't have any problems. I went to speedtest.net and had great results. About two minutes later the connection dropped, I couldn't connect devices via the Wireless router even though they were detecting the SSID and the signal was strong. My laptop would not connect even when directly connected. I took it back to the Bestbuy and exchanged it for another one. Same issue. After calling Cox the second time, I asked the IT person on the phone if they were receiving many complaints about this modem. He stated they have been getting a lot of calls and recommended that I get the SB6120 instead. I followed his advice and got the 6120 and a Netgear N300 Wireless router. AWESOME. Installation went smoothly and I have not had the connection drop yet! The speedtest.net results were absolutely amazing. Keep in mind that Im paying for 15 Mbps. Upon running the speedtest.net, I received 44Mbps Down and 9Mbps Up!!!! Wireless received 36 Mbps down and 7 Mbps up!. I recommend NOT getting this product. Buy the SB6120 and a wireless router of your choice instead.

Cuts down on the clutter, but...
I replaced a linksys WRT610N router and a ubee modem. Charter is my broadband provider. The equipment itself is attractive and decreases the look of clutter substantially. Installation was a breeze for my wired desktop. The instructions for changing the router username and password were ambiguous to say the least. A quick call to customer service cleared it up, however (8 chars. max w/o symbols for the pass., input prior password in last box contrary to the CD instructions). Now setting up the myriad wireless devices was a challenge at first, as no device (iPod touch 4th gen, xbox 360, netbook, tv, blu-ray player, network printer) was recognized at first. About 45 minutes of playing around with the interface (which is user-friendly when you get used to it) and suddenly all my devices were discoverable. Everything set up like a breeze, and for now I'm good to go. I'm also confident that my network is secure, and my speeds seem to increase on the speedtest.net web (18Mb service, getting 30Mb!), although that was one test. Provided it doesn't drop my device discovery or my speeds, this was very well worth the money.

Review by SLB ().
Seems good, just not for Cox...
Well, bought this modem despite the mixed reviews. Got it home, was very easy to hook up, and seemed to work right away. Went from getting about 20 Mbps, to 50 Mbps right away with good signal strength and range. Then the disconnects started. Sometimes it would work... Sometimes not. Some web pages would work, others not.... After calling back my ISP (Cox Communications), they referred me over to Motorola. The Motorola guy said that there is a known compatibility issue with Cox internet service, and right now, all they are doing is to offer refunds to people who have bought them. Cox had no idea there was any issues. So, if you have an ISP that this is compatible with, seems like a great modem/router, but otherwise it's an expensive brick.

Not a best buy
I bought this modem after using one at a friend's house that worked very well. Installation was very easy and I was up and on the internet very quickly. After a couple of days, the modem has started bogging down, instead of getting the 13 to 16 meg down that I was getting, I have gone as low as .2 meg down. After rebooting, it jumps back up to the faster speeds. Also, the wireless lan is awful. I am about 20 feet from the modem and my connection is only good, about 1.0 Mbps. For a modem/wireless router that is supposed to deliver true n band support, this is around 1/150th of the performance expected in n band. My Linksys E1000 delivered well over 100 mbps.
Review by RPTagg ().
I have had this "modem/router" for the past 6 months and can say this is the worst router I have ever used. The speed is ok at best, but that is if it is working. I have had issues with it dropping at least 5 times a day and it has done it multiple times in the middle of my timed college algebra quizzes. I have had service technicians from Cox Communications at my house 3 times now and they cannot figure out the problem. Turns out it is just this piece of garbage. DO NOT BUY THIS unless you want guaranteed problems!

Quality Wireless Cable Modem Gateway
Had the usual separate modem and router (modem 3 yrs old and modem 2) and have Charter service. Went to Netflix a few months ago so streaming became important. Because of slow internet could not buffer fast enough resulting in movies stalling. Charter speed test showed much lower download speed than package I have. Purchased the Motorola, followed the instructions and set up was a breeze. Repeated speed test many times and consistent max downoad speed. Streaming now works great. Could not be happier with my choice.
Review by Gus2 ().
The installation was easy but the performance was not up to par. The modem fell off the network 5 times in a span of 5 hours. Too much for the first day it was installed. We removed it and will be returning asap. We installed our original old modem/router set and they worked fine which tells us it was definitely the modem.
Review by Randy79 ().
Ok so I bought this to replace my G network and it was an AWEFUL experience! I bought this because the best buy guy recomended it over what I had origanally come to buy (which wasn't even at the store) and I was pretty excited. I go home and look at the instructions which were just aweful (6 boxes that looked like a 1st grader drew). So I hooked it up and after an hour of tinkering I finnaly called Comcast (which was the ISP table this was on) and went through about 30 minutes of them setting it up. So that was horrible. So after all of that the internet is more unreliable and unstable than my 6 year old G network setup. So I used it mostly for my Xbox and it cut out every 30 minutes or so. My Ipad wouldn't even go to google and it was just annoying! So today I finnaly snaped when randomly it just stoped. So im back to my G network (which is faster than this hunk of junk.) SO my advice is DON'T BUY THIS JUNK!

Didn't even last a day
I bought this modem to replace the Motorola SBG901 from my cable company. I called the company they rigged it work and it put a good wireless signal. It lasted only six hours before it quit working and the cable company tried to ping it and it never responded. It was worthless ! I had enough and returned it for cisco wireless router. I went back to cable company and got a regular modem. Hooked it all together and got great signal and range in my home. Do yourself a favor ? Don't waste your money on these all in one modems. They just don't work, for me anyway.

Don't get until they upgrade firmware
I purchased this about a month ago. Was a bit weary since it had not received good reviews. Well it turns out, the modem sucks. I say this because it lost connection every time my computer woke up from sleep mode. My old Motorola modem never had this problem. It looks like it's a firmware issue and Cox said that they didn't have any updates. They said that any firmware updates get pushed over every night. So, good thing I kept my old one. I am returning it to BB today for a full refund. The only good thing is that the speed did increase, but that's about it.

BEST CABLE MODEM
I purchased this cable modem and installed cable modem and it fine working. It is very faster speed download and upload. Wireless network works fine with my printer. There no problem cable modem. I don't like Linksys E2000, E3000 and E4200 because too many problems. I am happy with Motorola SBG6580 cable modem ?

Will not buy another one
The modem operated fairly well for a while. Right after the warranty expired I began having problems. The modem required rebooting every day. The furthest it would broadcast a wireless signal was about 20 feet direct sight. I would look for a different modem to buy.

Great modem despite poor reviews
I was afraid to buy this modem based on the terrible reviews here, but i decided to try it out anyway and i could not be happier. I had it working in less then 10 mins out of the box. Easiest set up ever (and i have very little computer knowledge). Great reception from across my apartment. Motorola also has great tech support. This modem is amazing.

Who is your ISP?
Bought 2 weeks ago when Charter informed me my Linksys modem (Docsis 1) was no longer supported. The 6580 was on their supported list. Hooked up easily. That was the end of the good news. It dropped the signal every time I walked away from my computer. Voip phone would not work on long distance. Wifi radio stopped all the time. Packet loss ran 60-80% consistently. Would not reboot on its own. Charter tech, Motorola help, all said signals and specs were OK. To check I bought a cheap used Ambit (Ubee) modem, the one sold by Charter, and it works great. So I don't know if the problem is with me, the 6580, Charter, or an incompatibility between the two. I advise you don't use it with Charter. If you want to try one anyway watch Craigslist and you may see mine there as I threw the box and can't return it.

Excellent modem...but careful with Cox Internet
Bought this modem to upgrade from my Surfboard 5101 which has been a stellar performer for a number of years. Spent 2 days struggling with signal being dropped after a few minutes or couple of hours. After several calls - Cox insisted that there was nothing wrong with their service and Motorola kept pointing to the high upstream power level (57.5 dBmV) as the culprit...Called Cox to get them to switch back to the old modem and presto - the tech on the line diagnosed the problem as being old firmware shipped by Motorola (3.1) - He upgraded the modem to 3.2 firmware and off we went....Very disappointed with Motorola tech service, which was quick to dump the blame on Cox. I am getting about a 20% increase in download speeds - approximately 30 MBps (Premier with Powerboost). If this thing craps out one more time then this is going straight back to Best Buy.

Supposed to be plug and play won't work
Cable guy tried, I tried, Motorola help call. Still can't log on after a week. They ship it configured for max security and I have been told it won't work with XP. Seems to me you should ship it so that it works with 99% of computers and let people increase levels of security AFTER they get it working. Most user unfriendly interface I have ever seen. I am sure that it works perfectly with some computers but I don't recomend rolling the dice if I were you. I purchased the most expensive because I didn't want problems like this.

Easiest modem I've ever encountered
I have just had this one day and love it. It has been the easiest modem or router to set up I have ever had and the speeds are blazing fast. I have 2 laptops my palm pre plus and my Hp wireless printer hooked to it and all did great the first time And just think all this in a camper..........Got to love technology. . I hope I don't have the problems that others have stated but so far I love it. I'll post updates as time goes on.
Review by anealysr ().
I bought the SBG 6580 because apparently it is the only combo that works with Comcast. I have had four, yes four, of these devices from Motorola. All have the same problem- hopeless coverage. It cannot give a full strength signal even if the laptop is right beside it. If I move a 20 feet away the signal drops away- sometimes loses it entirely. Set up is bonkers as the first reviewer noted.
Review by Selig ().
It really doesn't work... Really...
I wish I could give it more than one star because, in my opinion, the rest of it is fine. It's a home device, and for that, it actually does quite a lot. There are a couple of quirky things that make no sense (like the prompts for changing the admin password is totally beyond comprehension), but that's not the issue. The issue is that a great idea, and a great company, put out a product that's a bloody disaster. My experience matches so many others. Works great, then stops. Once it stops, it's about as useful as an AMC Pacer (sorry Pacer enthusiasts :-). Mine started failing by the wireless component simply disintegrating. It stopped working all of a sudden, but not for every device. But if you could connect, it wouldn't necessarily pass you through to the WAN. If you couldn't connect, the failure would be unreachable device, no response or your PSK is wrong (it's not). After hours tweaking it and coaxing it (to the point of removing all security and threatening it with bodily harm), the wireless came back to life (but I also had to rename the SSID... Huh?) This was a short-lived victory (if you can call it that) since after that, it went to the next level and started dropping the entire cable connection multiple times per day. The only recovery is to pull the power and let it reconnect. Then you have internet for anywhere from 30 minutes to 2 hours. Unacceptable even if you didn't have electricity. No chance for redemption, and the dream of the space and outlet savings of an all-in-one is toast. replacement will be a stand-alone modem that has reliability (like it's Motorola brother) and a router like a Netgear.

Unless I am inside the same room as this modem, my connection keeps dropping and mostly wont even let me connect. When I go to the same room as the modem, works great! Very frustrating when my old Linksys worked beautifully while laying in bed. Furthermore, took me over an hour on the phone with Comcast to get this to work. I will be returning this item.

Great wireless cable modem.
WPS really simplifies the installation process if your wireless devices are so equipped. Adding all the wireless devices in my house was a breeze with the exception of one. My sons computer was using a Belkin USB wireless N adapter. For whatever reason the Surfboard could not connect to it. The activity light on the Belkin adapter would flash when the Surfboard was trying to connect, but it would fail to find the Belkin adapter. Since the computer is close to the modem I just ran the ethernet cable to the computer & called it a day.

Set up Fast and Easy
I was very unsure about buying because of the bad reviews, but after talking to motorola I thought I would give it a try. I wanted the most current technology and this is it. I plugged it in and sync everything and so far (have had it for over a month) it has worked perfectly.
Review by QueenofChange ().
Well Constructed, Fast & Highly Dependable
I purchased my modem in August and have had no problems with the equipment. However I have experienced a number of issues with poor performance; which when researched thoroughly have been due to faulty equipment in the main trunk lines in my area. Once the faulty equipment has been located & replaced by Comcast on the trunk line each time my service has been exceptional afterwards. In each instance Comcast has taken 30 days and numerous service technicians working with my to identify the issue. And in most situations has had me swap out perfectly good equipment to isolate the cause of the problem residing on their side.
Review by BabyFox ().
Been using it for about a month now without any issues. I have the lowest speed available by cable company (1Mbps)and it works pretty good. videos are slow loading and some don't play that good because of my cable speed, not modem.Thought cable company couldn't control speed and this modem would give me max speed, WRONG! But I like it anyway. Easy setup with cable company Charter Communications.

The biggest problem with this modem is that it ships out with the extremely buggy 3.1 firmware, and you are entirely dependent on your cable company to upgrade it. Most cable companies will not tell you what the update cycle is so you are stuck with the poor performance of this unit as is.... Download speed is good, BUT ping time, latency, and packet loss is unacceptable (rated an F on pingtest.net)... Get a different one... stay away from the 6580...
Review by AlexM555 ().
I bought the SBG6580 a few months ago to replace an aging Linksys WCG200 gateway. The Linksys had been fine, and it got me addicted to the all-in-one concept, rather than having a separate modem and wireless router. I never had much trouble with the Linksys most of the time I had it. However, it did seem to be starting to "go," with more frequent reboots required toward the end. So, I checked my ISP's web site (Cox) to find out what wireless gateways were on their "good guy list" and I found the SBG6580 on it. I was very interested in upgrading from wireless G to N, and a quick search of Best Buy's site told me that my local store had the SBG6580 in stock. I found it very easy to set up, and I started running speed and ping tests on it to see if it was really "all that." The ping test revealed some issues, and after some quick research, I traced it to the "IP Flood Detection" checkbox on the Firewall page. I turned that off, and BOOM, I was off to the races! I just checked the Status page, and the gateway has been "up" for over 72 days without interruption. I heartily recommend this device.

Pros: Motorola quality, easy to setup and use, all in one unit, everything needed is in box.. Cons: SUPERCALAFRAGALISTICALLY AND UNREALISTICALLY OVERPRICED, WIRELESS RANGE SUCKS !!! If you do not care for the single unit, get separate modem and wireless router for lesser cost and better operating range. I just HAD to get all in one unit.

Easy Installation - FAST Performance
I upgraded my Charter internet to MAX, which is 25 Mbps. I needed a combination cable modem with 4 LAN ports, and the WiFi is a plus. The unit installed in minutes, Charter accepted the MAC, and away I went with 36+ Mbps compared to my old 5 - 7 Mbps through a DLink DCM 202. I am happy to have decided on this modem (SBG6580) over the 6120.

A Very good product! Worth my money!!
Despirte all the bad review, I purchase it at my local BB store anyway for $134. I recently purchase the $99 Motoralla Wireless Broadbrand Modem which only has one ethernet port and I didn't want to buy a switch. I use it for 1-2 week at least and decide that it won't work cause I will be getting a PC. I need extra ethernet port. So I read some review and Bought ithis Modem anways. Why you ask?? * 4 ethernet port *Wireless * Broadbrand Modem A 3 in 1 ..who else won't want it??! I didn't want to buy two equipment and use two power outlet...no no no.. I rather save energy and use just one. Setup was a breeze for me, the CD wizard I think isn't need but that is just me. I have to call my ISP cause I didn't write down the old modem MAC. For $134, this will last me for quite some few years plus I don't have to pay Charter $5 each month!! HAHHAHA!! Wireless signal on my PS3 average about 50%+ which is by the living room about 4 room so its not bad. I have place order to get CAT6 cable to use with this so the date would be faster, cause the modem only comes with a CAT 5e.

Waste of time and energy
I read the reviews, and since the overwhelming majority warned against this modem, I was leary about buying it. But I wanted to try and save a few bucks buy owning a modem instead of leasing from Comcast, and I wanted one part, instead of a modem and router. Well let me tell you, this thing is going back to BestBuy today. At first I was impressed. Set up was easy, the wizard did it all for me with relative ease and had me up and running with Comcast Xfinity in no time. I set up a wireless network for two computers in the same room as modem within 10 ft of it. All was good until it was up and "running". Within two hours, my wireless connections became intermittent connections, on and off. Surfing was a nightmare and pages loaded about 50% of the time. When it does work, it's not as fast as advertised. Direct cable to the old modem was very fast ...this is snail pace, that is when there's a connection. Hope this helps, if you do buy, I'm afraind you'll be disappointed.

Easy to set up. Called ISP to change MAC Identification number. Connected to a computer via ethernet cable to confirm that it was working, and I was ready to go. Download speeds are much improved. I recommend this gateway.

Always looses signal
Within the first day I was having to reset the gateway as it was losing signal or getting slow download speeds.

Do your research
The modem was a real royal pain to setup. The local ISP server could not get the modem to work at all with their network. All the perninent address and information were provided, but their network was not able link or "see" my IP address. The wireless network router portion was a neat idea!!! I had to call the tech support, and they were able to help greatly. Overall, I could not get the thing work with the internet, and had to return it the store, and get my money back!!!!

Purchased this to replace my DSL with integrated wireless modem. Wanted D3 cable modem and integrated wireless in small package. Very simple install and great support from Cox. Was impressed to experience 50Mbps+ in the downstream. Wireless coverage is as good as my previous modem. Been using this modem for 2 weeks with no issues.
Review by InfinityandBeyond ().
DO NOT BUY THIS PRODUCT!!!!
I read the reviews and since there aren't many options in the market for a wireless cable modem I wanted to try this anyway. DO NOT WASTE YOUR TIME! Well, the first week it was perfect, the wireless signal was 97% throughout the house. Yesterday I had to reset the modem since the internet was down, wired or wireless. During the day I played PS3 and the connection dropped every 30 minutes. Today the same happened, no internet at all. I had to reset the modem again and then the PS3 signed out every 5 minutes. This thing is going back to BB today.

Don't buy it
The wireless sucks! I had a Motorola 3347 in the exact same place for over 2 years, never had to power cycle it one time, never dropped packets signal was steady . I Have had this modem for 2 months and have had to fight with it on a daily basis. drops packets, poor throughput, poor signal strength. The default firewall settings blocked lots of traffic, Had to do many tweeks and it still preforms poorly. I bought this modem because of Motorola rep, but would not recommend the surfboard extreme, it is a extreme pain in the rear and have spent too many hours trouble shooting it's problems.

THIS IS THE WORST WIRELESS MODEM!!!!
I got this from Time warner as a lease, and we finally got the ability to use DOCSIS 3.0 speeds in my area, I was really excited but when I tried to do a pingtest on Speedtest.net I kept loosing Packets, so I figured it out, the firewall settings on this will cause you to have drops in speed especially while playing games, so I went into the Modem settings and it was the IP Flood Detection when it was enabled it really caused you to have alot of drops, I wasn't sure if this was safe to turn off so I left it off anyways, but I went and purchased the Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem, I just got it today so we will see, but I also have a Netgear WNDR3700 Router and I am gonna test both together with the one I just got and I will post an update soon on the outcome, but DONT BUY the SBG6580 model HORRIBLE!!!!. I hope they fix this problem in a future firmware update. Update!!!!! I just got the new Modem and it's AWESOME!!!! no drops, I recommend the SB6120 model

Great out of the gate, dies on the home stretch
I waited until my second one bit the dust before I wrote this review. I've owned two within the past four months, if you are one of the lucky ones, good for you but if you are a potential buyer play the odds based on all the reviews and stay away! I was enticed by the bundled functionality and believe me I've given Motorola the benefit of the doubt, they have great customer service but the product is not ready for prime time. I have to reset it three times a day, the first one did last longer than the second. The second went into "reset me please" mode after about one week.

Tethered Wireless? Wow!
My mother has a business adjacent to our home and we share the internet with both her business and the home. The netgear we had prior boasted 54mbps... worked great other than having to reset it time to time. Thought we would spring for this one, best of both worlds if you will, router and modem. Nay, I tell you! Nay! 5 feet....goes from excellent to low.

The unit worked very well for a few months, then began disconnecting and does not reconnect easily. Terrible product.
Review by pblythe ().
Don't buy this dud
Don't buy it--go with another brand. Easy to install and worked great for the first couple of weeks. Gradually, signal strength decreased, and it started to disconnect more and more frequently. Even better is Motorola's customer service--pay to get a replacement with the same defective product and wait 5-7 days for them to ship you the replacement. Definitely return to Best Buy before the warranty period is up if it starts disconnecting--it will only get worse--and Best Buy treats customers much better than Motorola. After this experience, I won't even consider a Motorola product again.

Beware of problems down the road
At first, I was very happy with the all-around performance of this modem. Aside from the slightly clunky interface and the auto default ON 'IP Flood detection' (which will slow your modem drastically) I didn't have any complaints...even with the once or twice a day random disconnect. Now, just over a month later, I am fighting DOZENS of daily disconnects. It has gotten so bad that I can have 8+ disconnects every hour. Comcast says the modem signal strength is excellent. They also said it is likely a hardware problem with the modem. So a word of warning to anyone considering this modem. It may work great for awhile, but it also may cause you endless frustration with continual disconnects and reboots. Good luck!

Easy set up for beginners
Installed with ease. No problem setting up. So far works great.
Review by HeyD ().
Super easy to hook up with Comcast. Must hook it up through the Ethernet connection 1st. You CANNOT do wireless setup until its registered through Comcast. After you select "wired setup" it takes you to the Comcast website to finish the install. It registers the product through there website so you can use it. After its registered through Comcast, go to motorola's website 192.168.0.1 ----- User:admin ------ Password:motorola ----- to set up the wireless on your computer. hope this helps all who bought this. This is SUPER FAST!! Download speed are faster then Comcasts ratings with this modem.

An excellent upgrade to my old modem and router
A good combined unit. Basic installaiton was quick and easy. Fast and reliable connection with COMCAST. Wireless coverage throughout the house is as good as my old Linksys router that used a remote external antenna. While there is some built-in HELP, it is not very comprehensive. Some of the more technical options are difficult to setup without additional knowlege.

Do not recommend
I'm experiencing a lot of the same issues that a number of other people who have purchased and rated this product. Wireless is very poor even when the other machine is within 40 feet. My machine is plugged directly into the unit - which sits 3 feet away - and I still get very poor performance. It has also "hung up" on me twice and it's only been installed for 2 weeks. So....I would strongly recommend that you consider a regular cable modem and router...not this conbined unit. I'm very disappointed.
Review by myfifteenthtimeforaname ().
Overall, Very Good Stuff
It's blazing fast for Wi-Fi, easily customizable and no problem at all to install. I'm having some issues with the cable internet provider, so if/when you install your new Surfboard, have a chat with the Tech Support guys at your ISP and make sure all the setting are right - it helps to log in to your modem (usually 192.168.0.1 on your http dial) and go over the details with them just to make sure. Other than a rocky start with the connection sometimes failing, once I got the settings right, it's performance is excellent compared to other wireless cable modems that I've used.
Review by matcheydj ().
Should have read the reviews first...
All of the one star reviews are correct. Hopefully they get this thing sorted out, but it's not ready for prime time. Several calls to Motorola tech support and Comcast tech support couldn't sort out the problems with this modem. I didn't even get as far as testing the Wi-fi part that people complain so much about. Comcast tech support figured it to be a DNS issue. Web sites were extremely slow to load and about 1/3 of the time the pages could not be displayed. We tried lots of different setting and all to no avail. I returned it and bought a Motorola SB 6120 and a Netgear N600 Wireless Router--both of which have very good reviews and I see why. I'm bummed that the all-in-one modem/router thing didn't work out, it would have been much more convenient in terms of managing cable clutter and desk space.

Trust the negative reviews - Do NOT buy this
I'm normally a skeptic when it comes to negative reviews, mainly because I've bought products with bad reviews, and they turn out to be pretty good products. NOT SO HERE... I bought this to replace an old DOCSIS 1.0 modem since I just upgraded my speed on my Suddenlink account. I also wanted to do away with 2 pieces of equipment (modem AND wifi-router). It seemed that everything I would plug into the switch ports on the back of every wifi router I tried gave nasty RFI on my ham radio equipment. This still gives RFI. But, that's not why I'm dissatisfied. THE WiFi IS TERRIBLE! If you get more than 20ft away from the device, your speed drops around %50. If I walked into the bedroom, the download speeds would drop from 15mb to around 6-7mb. I tested out pings with my iPhone. While in front of the modem, ping times were around 6-14ms. Walking 30ft into the bedroom, the pings shot up to +50ms, and began dropping replies. I tried this 3-4 times, and same ever time. If you drop even one bar in signal strength on the wifi indicator on either the laptop or iPhone, the speeds drop, and the lag kicks in. I put the device into it's pseudo-bridged mode, hooked up the wifi-router I was using, and it's a night/day difference. Same iPhone, same app, pings were constantly down around 4-11ms from in front of the router to all the way to the furthest point in my house, with absolutely NO dropped pings and no noticeable speed decrease in downloads.. I'll give the modem this. It's faster than my old docsis 1.0 modem. That's about the only good thing. Save your money, get a good wifi-router and a simple docsis 3.0 modem. This is NOT an answer to our needs of getting rid of network components. My other gripes are that the configuration interface is clunky; nothing seems to be where it needs to be, and trying to get the stupid thing to get into it's "bridge mode" took nearly 30 minutes and multiple resets of both the modem and wifi-router. It's nothing a noobie is going to be able to figure out. I REPEAT! Do NOT buy this! You can spend less money buying a simple DOCSIS 3.0 modem and inexpensive wifi-router and get much better wifi performance.

Easy Setup, Fast Wireless, Great Gigabit Port
I was using a Linksys cable modem (Docsis 1.0) and wired router and wanted to consolidate the two into one. Motorola had the only solution I required. The first one I bought was already in Comcast's system so I had to exchange it for another one. I guess someone used it and returned it. The setup for the second one was simple. Downloaded the Comcast configuration software, connected the cable to the gateway, ran the install software from comcast and bam, setup is done. Took 15 minutes. Features I really liked was the following in no particular order: - DOCSIS 3.0 - 4x 10/100/1000 Gigabit Ethernet Ports - Dual Band (2.4GHz / 5GHz) - 802.11a,b,g,n - WPA2 (AES), WPA2-PSK (AES), 802.1X (EAP-MD5/TLS/TTLS/PEAP)

Speedy, but only on 1 Band
I just got done returning this product (SBG6580 modem/AP/router). It was actually a great product. My download speeds increased quite a bit compared to my previous setup - Moto SB4200 + Netgear WGT624. The range was good on the wireless, at least as good as the WGT624, which I never had a problem with. I had it running for ~4 days, with no connectivity issues. Two problems, though: first, the interface for doing all the setup (didn't try the wizard) was a bit clunky, even doing things like changing setting on a different page if you made a change on the current page that disallowed the function. Once I understood what was allowed in each mode, it was easier, but I was confused for a couple hours. Second, and this is my main complaint, is that the dual band (2.4GHz, 5GHz) function isn't simultaneous. You can run at 2.4, or you can run at 5. If you choose 5, you only talk to 5Gig 802.11n devices and 802.11a devices. Any g and b devices are dead. I was hoping to set up my 2.4 devices on the primary network, and the 5G devices on the "guest" network, but there's only 1 control for the network frequency, and it covers both networks. So, if you would be happy with a speedy modem/AP/gigabit router at an awesome price that does EITHER 2.4GHz or 5GHz, buy it. if you want simultaneous dual band, look elsewhere (I'm getting a SB6120 and a Netgear WNDR3700)

Trouble from the start
I wish I would've read some of the reviews before purchasing this modem but let's just say I ran into some of the same issues. I could not for the life of me get my desktop, which is hard wired, to work but my wireless laptop worked fine. The next day my desktop worked but the laptop would not recognize the modem. I only had this 2 days and that I experienced enough pain and suffering to know a bad product when I see it. I'm going to switch this out for the SB6120, which has received nothing but good reviews, and keep my CISCO 3000 for wireless.

Not ready for prime time
I bought this to replace an old, stock Comcast modem. It was advertised as a top of the line Docsis 3.0 modem gateway, with a built-in wireless router. If only. Unfortunately, after a week of fiddling and several hours online with Motorola support, this product did not meet expectations. It failed miserably as a wireless router, and was inconsistent as an internet connection for a Panasonic DMB-BD85K Internet-ready Blu-Ray player. I must give kudos to Motorola customer support, though. They tried, tried and kept on trying to make the wireless router work properly. I disconnected the 2.4GHZ phone. We adjusted every adjustable setting. We changed the encryption to the least secure; we turned off the redundant firewall. We set the wireless to Channel 11 instead of 1. "That didn't work? Try working down the list (10, 9, etc.) ..." Alas, no channel gives more than ten (yes, 10) feet of wireless coverage. The Motorola's wireless signal cannot be detected beyond the room, despite the fact that a Netgear N300 router can penetrate 3 floors successfully in my home. As a last resort, I attempted turning off the wireless entirely and just hard-wiring the product to the Blu-Ray player. Neither of the two TV shows I downloaded from Amazon VOD played all the way through. I ended up disconnecting and reconnecting the ethernet cable, and grabbing a different one from another from my DSL router upstairs. Same problem with the second cable. Funny, though, I watched two TV shows without a hitch with the Comcast modem + a G router. So it's almost positively not the Blu-Ray player's issue. Sorry, Motorola. It's going back.

Excellent Modem, All-In-One Wireless Unit!
I bought this modem to replace my Cablevision modem (a/k/a Webstar). 3 reasons for this: 1) Cablevision has substandard gear 2) They like to give you used, nasty, refurbished units. 3) I rather have my own equipment, without having to worry about replacement fees, etc. Now, here's why you should get this modem as a replacement: 1) A speed increase of at least 2X (DOCSIS 3.0)! 2) STABLE connections (no dropouts). 3) Wireless built-in; you don't even need a separate router! This unit works FLAWLESSLY. My experience, so far, has been nothing short of EXCELLENT. I initially plugged in the unit, then had to call Cablevision to get the modem registered. After a successful reboot, they registered the modem and I was online in minutes. Previously I was running the Motorola SBG900 (older model from many years ago). This modem would drop signal after 40-45 minutes, then reconnect in 10 seconds. I was so frustrated, I went out to purchase this, and have never looked back since! The new modems (like the SBG6580 here) are the latest, DOCSIS 3.0, which gives you greater connectability, along with enhanced speed! Security setup is a snap - or a workaround, depends on your situation. The great thing about this modem is you don't even need to type in any codes for the wireless to work right out of the box. All you have to do is to click on the network in Windows, then the system will prompt you to 'press a button' on the modem to connect. It's that simple! For most users who just use the service with a laptop, etc. this will be all you need. Now, if you want to connect a Wii, cell phone, blu ray, etc. off the network, you'll need to setup an access code. To do this, you type 192.168.0.1 in the address bar, type 'admin' for the user name and 'motorola' for the password, and follow the instructions provided online at their website (motorola.com)... look for the 'User's Guide'. Click 'Wireless' at the top, then look for 'Primary Network' on the left. A great purchase! I won't be returning this! Anyone looking to BOOST their service, and get the wireless router BUILT-IN, check this out! It is an absolute wise investment!

If you get one that works it is a good product
I bought this modem last Thursday. I have a Windows 7 laptop and and Mac laptop at home, plus a printer and a couple of phones that access the network wirelessly. Rather than using help from Comcast to set it up, I called Motorola. The guy walked me through the process and the wireless modem worked great for about ten minutes. The Mac continued to work with the modem, but the PC did not. It could see the modem and it would tell me the signal was fine, but would not reconnect with it. So I called Motorola back and the guy explained to me that it was a Windows 7 problem. I then spent over an hour on the phone with two guys from India who supposedly fixed something to make it work. Based upon what I saw them do on the screen, they did not appear to make any changes to Windows, but rather only appeared to work in the motorola set up screens. In any case, neither the Mac or the PC worked the next morning. So it probably was not a Windows 7 problem. I called Motorola and complained and they suggested I return it for a new one. The Motorola person told me some of the modems were sketchy and people were having problems wirelessly reconnecting after their computers had gone to sleep. Best Buy replaced the model without any questions. The guy at the return counter told me that they had seen a lot of these items returned. I hooked the new modem up and contacted Motorola, explained the whole problem and had the guy walked me through the setup. It worked great the rest of Saturday. It worked great all day Sunday while I watched football and tracked all my fantasy football stuff on line and my wife watched netflix. Everything started up just fine on both machines on Monday morning. Hopefully, I have a good modem and my problems are solved. Based upon my experience, what I have read in the other reviews and my discussions with Motorola and Best buy employees, it appears that Motorola failed in one of the following areas: Testing, Management Decision Making or Manufacturing. It is obvious that there is some sort of problem with many of these modems and the Motorola help desk is not up to speed on how to deal with these problems. All in all, I had three different Motorola people walk me through the setup and all three set it up a little differently. I went into Best buy simply to replace my current Linksys wireless router and bought the much more expensive modem partly based upon the Motorola name. Owning my own modem saves me $7 a month that I do not have to pay to rent the comcast modem, so if this baby lasts two years, it pays for itself. Unfortunately for motorola, I will not trust their name as much in the future. It is so obvious that Motorola failed to adequately test these boxes before they released them. Don't know if the problem is in their QA area, their manufacturing area or bad management, but ultimately, some manager somewhere in Motorola made some wrong decisions. If you buy this modem there is a good probability you will have problems. Be prepared to have to return it for a different model. If I have any more problems with this modem I will return for a full refund and find a different solution that does not include a motorola product. I could not recommend this product to anyone without some cautionary warnings. Be prepared to return it and be prepared to spend some time on the phone with help desks.

Works Like a Charm
Brought it home two days ago, hooked it up and it works great. Had a little trouble configuring the settings for my private network but found everything I needed in the instruction manual. I do not know why so many others are having issues with this device... I think this unit is a great price, it replaces three devices: Cable Modem, Switch, Wireless Hub. You can now buy some of these items together as well, but not all in one place like this. My only guess on the others is a faulty unit. I recommend giving this a try and if you have issues, return it. These reviews just seem to be to polarized to be accurate all the time. I also factor in that most people who are happy with something like this are not going to post anything at all, so the average score goes down...

Good all in one with Wireless N
I have 10 devices connected and they all work great and without trouble. I do have excellent signal strength throughout the house. I also found the admin options on the the router to be very robust. On the downside, Comcast had lots of trouble getting it provisioned. I invested about 4 hours over 3 days of calls to get it provisioned. They did not have the residential provision codes and told me it was a business modem and asked where did I buy it. Ultimately, it was escalated across many people and it got resolved.

I am pretty much sure this router should be called back from market. Motorola company should be ashamed for introducing such useless product in market. It has connectivity problem and you move from one room to other and you connection drops and you get one bar at max sometimes. Even when you are sitting with modem sometimes you see three bars in wireless signal. dont buy as i feel this technology has still not matured.

Swithed from DSL to Cable and had this Modem running quicker than the time it took to connect the power and Cable. No Losses of Connectivity unlike QWEST, and I get 5.76mbs Download/ .97mbs uploads.

Finally a wireless cable gateway that works.
I have tried using wireless gateways and routers in the past with my cable internet service but no matter what I did, I could only get things working for a few hours and then suddenly I wouldn't be able to connect wirelessly. It would actually take more time to get it working than the service would stay available to use so I finally gave up. I got this modem last weekend, spent 15 minutes hooking it up and activating it with Comcast and haven't had a single problem since. I also don't know what is going on with the other reviewers who have complained about signal strength. I have central "smart" wiring in my house so the modem is in a steel enclosure in the basement and I get 5 bars of signal anywhere in the house, including the garage.

Useless for wireless
A first class modem and lightning-fast ethernet router (for PC and Xbox 360), this unit is let down by an extremely weak wi-fi transceiver. I don't know how Motorola could have got it so wrong. 10 feet away from the unit and 3 laptops (HP, Dell and Sony) all got at best (AT BEST !!) 1 bar signal strength. After dropping the laptops of the next work 4 or 5 times an hour all of the first day we had it, the unit was returned, as defective, to Best Buy the very next morning. Fortunately, the store made no quibble about this. Instead, we picked up the rock-solid Motorola SB6120 Modem (the same modem as in this gateway unit) and a Netgear WNR3500L RangeMax Wireless-N Gigabit Router. The new combination was dead easy to install (plus you get to choose your own WPA2 security key) and we get a 4 bar Wi-Fi signal at the furthest-away point in the house. The Wi-Fi data transfer rate is excellent for sending/receiving HD video and the ethernet connection for Xbox Live is blisteringly fast, with no detectable lag and no drop-off the network during the 6 hours we were logged on.

Not ready for prime time
It is on the comcast approved list, but took 2 shots to activate it. The first tech I got was clueless, and failed. Wanted me to take the modem to a service center... Simply called back got another tech, who activated it w/o any further issues. In all fairness, I did not see any of the weak wireless N or other sporadic connectivity / performance issues other people complain about. It is pretty versatile in supporting wireless N, I get 300 Mbits from most of the diverse equipment I have supporting N. Supports either TKIP or AES, However: The modem lost connectivity after a few days, and had to be reset to factory defaults. Worked OK for another 3 days, then hard-hung, Could not connect to it from the NAT side, via wired. (All lights off, except power and wan). After a reboot, it is now working again. I notice, before it hung, I have seen dozens of event log messages about T3 ranging errors and the modem being unable to get TOD ( time of day) from the ISP, in a short span of a few minutes. Come to think of it, I have seen these messages coincident to the previous episode of lost connectivity. Some theories I have gathered from googling this problem: 1) Overheating. Some people claim to point a fan at it and get better reliability. 2) Modem shuts itself down because it is unable to communicate with ISP headend. ( ie. the Event log messages are a relevant clue) This theory implicates the ISP. 3) Buggy firmware. The hard hung state, to me points in this direction. E.g. if the firmware code has a memory leak, eventually it could hard-hang like I seen it do, to be cured by a reboot. It sounds really good to have one piece of equipment doing both cm and wireless, but for a fundamental piece of your home network, this level of flakiness is just plain unacceptable. Your cable modem should work flawlessly, each time, every time, no exceptions. I am keeping it for another few days to see the problem repeat and collect some more data, but as soon as it hangs again, I am ditching it. I am planning to give Motorola tech support a call and give them a chance to troubleshoot and gather some info, as I would like to see this product fixed and fulfill its potential. If you have the time and patience, by all means give it a shot, I had a better experience than many buyers who complain. You can always return it, and that creates pain for Motorola that will lead to them fixing the problems faster.

Perhaps there is a quality control issue
I made an account on this site simply to review this piece of equipment. I know everyone says "I am an experienced computer user" but when I say it, I mean I am in charge of some of the largest stock trading systems in the world, as well as self-directed counterparts. Anyone who is a systems engineer for enormous server farms has likely climbed the ladder like me, starting with working on PCs for friends and neighbors, then getting a part time job, then doing residential support, then commercial desktop support, then corporate helpdesk, then junior SA, then senior SA, then engineer, then manager. I'm not tooting my own horn, I'm just saying that I have worn all of those hats and also have a masters in computer science. The point is, I know a lot about this stuff. This modem/router/wireless combo device has been a big headache and after a week of troubleshooting, I am pretty sure it has issues. Maybe I just got a bad unit, but my issue isn't wireless signal strength, it is data connectivity. It goes in and out, in and out, in and out, in and out... and this is while sitting next to the computer. Here is what I tried - Changed RTS and Fragmentation threshold settings. Changed beacon interval. Changed to all available channels. Disabled N Enabled 54g performance mode. Tried every security mode (including none). Verified it was set to 2.4GHz. Ping google.com -t and watched it drop in and out (even though signal was at 5 bars). Ethernet connection does work flawlessly (ping google.com -t for 5 hours). Called Motorola and they read off a similar list, none of which helped. Then I changed every available power option on the laptop side, changed WiFi card to "always on," and changed many of the options such as hard setting it to 54g and maximizing power, etc. Tried reinstalling and updating wireless card drivers. This laptop works everywhere else- Panera, my old house (cheap, 5 year old Linksys). Again, it always connects to the wireless but the data service is completely unreliable and intermittent. Just awful. I am going to return it to Best Buy but no Best Buy within 100 miles has one of these in stock, so I will see what I can do to find a better solution. Motorola said to take it back or send it back to them, but I just find it odd that my unit just happens to be defective.

Drops wireless connection when VOIP phone in use
I have purchased this to replace Motorola SB5101 and linksys WRT54G which were working well with 5 laptops(3 XP, 1 Windows 7, 1 Mac), PS3 and Vonyage VOIP phone. After an easy installation of this product, XP laptops and mac connected wirelessly but could never make it work on Windows7. Whenever VOIP phone is in use (incoming or outgoing call), wireless internet connection dropped on all my laptops. All the online work in progress is gone with unexpected connection drop! I have never tried PS3 with this modem. There was no problem with Modem functionality of this equipment but wireless performed very poor. I called Motorola customer service, they couldn't figure out what the problem is. So I have exchanged this product at BestBuy with Motoral SB6120 and Linksys E2000 for an additional $35. Everything worked fine with Motoral SB6120 and Linksys E2000.

Super Easy to Install and Super Fast Speeds
After having problems with my Linksys WRT160N crashing several times a day and resetting many times, i gave up and went to my favorite Boy Toy Store - Best Buy - to find a new router. As it happened, our Best Buy store had just received the Motorola SURFboard eXtreme Wireless Cable Modem Gateway. It listed for $149 but I was able to get it on the matching plan from my local cable service that had this modem listed on their web site that would work with the new upgrades. What I liked most was the fact that it was a higher speed capable modem, but also included a built-in wireless N router. The ease of the setup was so fast, I didn't realize it was done as there was no indication popup saying it was done. Minor issue once I figured it was up and running. There was no need to hook up hard wire ethernet first as it has the option for direct hookup with a wireless laptop. I went from 2 to 4 MGBs download and 1.2 upload... to 29.8 MGBs dowload and 3.0 upload. Of course my cable company already had the hardware upgrade done to accept the new modem/router.

was not compatible with Comcast
A Comcast Service Tech recommended this item to me. However, it ended up not being so. I never did get to actually use it so I wouldn't be able to fairly rate this item. I can say it felt as though it were made well, not cheesy. Also Motorola is a reliable company.

Excellent value - next generation DOCSIS 3.0
I purchased the SBG6580 several months ago from Best Buy and noticed it had a weak wireless signal. I didn't think too much about this as I had placed the unit next to my home media server, another external hard drive, speakers and a sub woofer and finally the desktop computer itself, all within a foot or so of the SBG6580. All this electronic equipment was surely the cause of the weak signal, or so I told myself. Recently I moved the SBG6580 to another location. However the signal strength did not improve at all, still in the thirty percent signal strength range. So I called Motorola, explained my problem, changed the frequency channels per their instructions as their technician stood by on the phone. Result - no improvement. Then something strange happened. Motorola told me my problem was of "high priority" to them and that a 'tier two" supervisor would call me shortly with a solution. The next day Motorola called and said they would send out a new unit, and that I should receive it within 5 to 7 days. It arrived three days later. I plugged the new unite in, changed a few settings, set up the security and now I'm happy to say I can receive a very strong signal everywhere in my house. However the most impressive aspect of working with Motorola support was the outstanding service provided. I would rate their response to my problem as a "10" out of 10. The Motorola SBG6580, even with the previous solved weak wireless signal, provided extremely fact access to my media files or when just surfing the web on my laptop. As a matter of fact when all three family laptops are in use at the same time there is no noticeable drop off in access speed or signal strength now. As for the Motorola SBG6580 itself it does everything it was designed to do, and fast. I have connected to it a Synology DS209 server. Also connected to the SBG6580 is the external hard drive. The SBG6580 can pull large 30 meg RAW photos for editing in Photoshop or viewing on my laptop as fast as my wired desktop. I have the 8 meg Express plan with Charter and this DOCSIS 3. unit consistently downloads in the 14 to 24 meg range. I would highly recommend the Motorola SBG6580, especially when backed up with their outstanding technical support.

Bad Wireless Connection
I thought the two-in one combo would be great; I'd used a 2Wire gateway before but was switching to cable from DSL and needed a new modem. This was pricey (paid about $130 for it). It was easy to install but I can't even bring my computer "around the corner' in the same room without dropping the connection. Heck, sitting 15 feet in front of the modem I can still drop connections (when my 2Wire gateway before had NO issues). Thankfully I shelled out the extra bucks to get the one that permits four hardwired connections. Still, they get used up pretty quickly: one to the PS3, one to the DirecTV box--leaves only 2. I have to use a 50 ft ethernet cable so my laptop can be "mobile" inside my apartment. When it's hardwired, the speed is fast, which (I think) has nothing to do with the modem and is all about Charter. For the price, the wireless connection should be rock solid and it simply is not. I would NOT buy this again; would NOT recommend it to anyone.

I could not wait for the stores to get the SBG6850 so I ordered it direct. Fast connection speed and setup was easy. Just Called Comcast and gave the the mac and was up in minutes. The only problem I have is the range on Wireless is terrible. Intermitant connections to my two laptops. PS3 connection less than 25 ft sucks big time so I have it hard connected as well as my office. I have another XP pc in my office running a D-Link Range booster dual antenna that works fine for browsing but gaming hangs on My granddaughter's online games hang. This could be the websites so I do not know. I definitely would NOT recommend this modem for what I paid.

Blows my Linksys away
Was almost turned off by the reviews but I needed something better than my Linksys WRT54G2 which I had already sent back for replacement and the replacement was worse than the original. Was on the phone with COX Cable for about 20 mins while we set it up and it was quite easy. So far, so good...time will tell.

Great Modem,router, and wireless gateway
I got this modem even though some people are saying its junk, wanted to try it any way, heck I could return it if i didn't like it. I love it, works great, Comcast installer came but ran a new line to the house, hooked it up, called the tech over the phone, and gave her the mac id and bingo it worked. the darn thing runs great. The wirless is ok but thats might be the fact that i put the modem inside my leviton 280 multimedia metal case. still get 4 out of 5 bars from the far side of my house. Very fast speeds wired or wirless. I would recomend at least with comcast. One cool and easy thing it when you press the small button in the front of the modem it sends the security key to the the laptop, or any other wireless device.

Fantastic addition, wonderful product
So surprised at the ease of setting up and getting to work. Ready and working in about 20 minutes. Simple and concise connection and set up a breeze.

DON"T BUY IT!!! We shouldn't HAVE to read or write reviews on a basic staple product like this, it should just work. Especially, from a well known and up to this point pretty well respected company (I recommend and sell Motorola everyday) in the business of communications equipment. DON"T BUY IT!!! Something like this should be PnP,unless you need advanced settings, Parental Controls and the like. DON"T BUY IT!!! This is my biggest wast of $ in years- DON"T BUY IT!!! From my experience, get your trusty BestBuy Clerk to point you over to something else! Maybe a Linksys - I've NEVER had a lick of trouble from their routers , and I've used alot of them at work, and at my family's homes. I really thought Moto would be great. Now, I'm not so sure of them.

Needs work, not great for gaming.
I bought this modem with good intentions despite the bad reviews but good intentions weren't enough to help this product. The fist week I had this modem was great nothing bad, except the N signal was weak. The N signal is as good as the B/G signal. The next week I upgraded to Comcasts Extreme 50 and It started losing signal than i had to restart the modem. At night when my Brother was playing games it lost it's signal. His gaming hadn't improved from the speed either I kept checking in on him to ask about lag and if their was a difference, there was none. I thought Switching my modem to a static ip addressing might work but, it wasn't any help. I also tried switching to B signal only but it kept reverting to a B/G signal or N. Hopefully when motorola gives the product a firmware update it will work better.

Comcast support / lemon
Comcast couldn't help me with this modem. I had to work with the folks at Motorola. They were helpful, and we got it going. But after only a couple weeks the modem started dropping the internet connection. I'd restart and it would work at 1mbps (very slow) and then die again. It would die every 10-20 mins. I decided to plug in the Comcast provided Scientific Atlanta modem and my old Linksys Wireless router and all is working perfectly. The Motorola all-in-one modem/router is not ready for primetime, and the folks at Comcast have no information about it. Also, when it was working, the wireless signal was weak. My 5 year old Linksys modem delivered a much better signal.

Great modem; don't understand the bad reviews
A huge improvement over my old Linksys pile of junk. Range is fine; works throughout the whole house. Speed is excellent. Only problem I had is that it took numerous phone calls with Time Warner SoCal until I found someone with the wherewithal to get it activated. Seems that it isn't on their approved modem list but can be activated by someone who knows what they're doing.

Works great and saves me money.
I bought this product so I would no longer have to pay the $5 a month lease to Comcast for the cable modem they provided. I almost went with the non wireless version after reading the reviews on here about poor range, but I have seen no such issues. The modem is downstairs and most of my wireless devices are upstairs. I get better signal stregth and data rates with this than the linksys n wireless I was using before this. I ran a speed test and I get 24Mbps both days I have tried it. I have the 15Mbps plan from Comcast, and my old modem tested at that speed so I am not sure how I am getting over that. I thought Comcast was limiting now based on the plan. Maybe they just misconfigured it to allow higher data rates than I am paying for. The only knock I have against it is that the wireless can only run on 2.4GHz or 5GHz adn not both at the same time. It is not a dual band like my old linksys wireless, but that wasn't a big deal for me.

Another great "All-in-One" from Motorola
I purchased this to upgrade from my old SBG900 gateway. My gateway is located with my home theater equipment so a simple clean look is necessary. I've been waiting for an all-in-one from Motorola that offered 802.1n for a while now. I've seriously been stalking this product online, waiting for it to become available. I have Comcast high speed internet right now. I usually average 3-5 Mbps down & 2 Mbps up. (over wifi) After installing this last night, my speeds were at 7.2 Mbps down & 2.5 Mbps up. I'm not sure yet if this can be attributed completely to the new gateway or if Comcast was just having a good night. I am very pleased with this purchase & it was a good way to "future-proof" my network for the next few years. I sold something on eBay last week that paid for this upgrade. It was basically free to me so it was worth every penny. ;-) However, if you currently have a decent 802.11g gateway such as the SBG900, it might not be worth the $150 you'll have to shell out for this. The benefits aren't really there yet. If you are looking for an all-in-one & don't own anything yet, spend a couple extra bucks & get this model. "But you don't have to take my word for it. (da da dun, Reading Rainbow sound effects)"

Very nice product
Im very happy with this gateway router, I had the prevous model sbg900 and this is a step better in every area and finally more than one ethernet port. I dont understand what these other reviewers problems are but my downloading speeds have increased by a mb which was a pleasant supprise since I mainly just bought it for the extra ethernet ports and my prevous model had to be reset every day.

This modem is not a good all in one device!
I am a Comcast customer. According to the Specifications of this modem, it supposed to be the top all in one cable modem available on the list of approved cable modems and EMTA devices. However, the actual performance of this modem can't beat the older version of Motorola (SB6120)... If you're looking for an all in one cable modem, this device may provide what you need. But if you're looking for a performance device, this is not one you're looking for. For example, the Motorola SB6120 + a Wireless N Gigabyte Router (about 50 buck) is way better!!!

wireless connection is very week
wireless connection is very weak, only 10 feet around keeping goot signal, when I moving to another rooms in my house it is loosing connection. I have called 2 times to tech support and did changes on modem settings, did not work. my old Linksys router working much better all around of house. I just want to upgrade my wireless network to N, but no luck.

Can't be activated by Comcast in Boston!
As of 7/11/10 when I write this review, Comcast in Boston cannot activate this modem. Although it is on their approved list of devices, it is not yet in their BILLING SYSTEM, so it can't be tied to an account. Doesn't matter that there is no billing for a customer-owned modem. I learned this the hard way, after a 1 1/2 hour call with Comcast. They have "put in a ticket" to get the modem added to the billing system, and will "email me" when it is complete. I give them a week, and then back this thing goes. Fair warning to all thinking of buying this modem. Doesn't matter how wonderful it is, it''s brand new, so make sure your cable operator has fully enabled it in your area.

Great Cable Modem Gateway
I bought this cable modem because it features Docsis 3.0 capability and also acts as a wireless router / access point. I just moved into a home that has Charter as the provider of internet. While I initially was not happy about that due to previous terrible internet, I signed up for the package. I wanted to rule out any possibility of a sub-par modem so I purchased this one. When the service was first installed, I was only receiving around 2mb per second on the download. I signed up for their MAX service of 25mb per second, so I was very frustrated. Upon calling Charter they told me they did not support the firmware for this modem yet. I installed a Surfboard 5120 and the speed was spot on. Later, it kept re-syncing and would not hold a signal. They told me it was too high of a speed for the modem. So as a last resort, I provisioned this modem with them again and it worked great. I believe it is all in who you talk to there and what they know about their jobs. This modem WILL work with Charter. The wireless piece of the modem works excellent as well and is very easy to set up and use. The interface shows all the modem information you could ever need as far as signal strength etc, but with your router features on the same page. If you want the best / latest consumer cable modem right now, this is it.

So far soo good
I have COX High Speed Internet and this modem is finally on their approved list of modems. I am replacing my old SBG 900 Surfboard which has served me well for the past 5 years. I've been waiting for an all in one cable modem with 802.11n and this unit fits the bill.
