How does this device compare to Motorola SurfBoard SB6141 and Motorola SB6121? I would like to buy this device because it's the cheapest DOCSIS 3.0 modem, but I feel like others, such as the SB6141 and SB6121 are better, though I don't know why. My ISP...

It works very good with Comcast in my area (Phillys). I don't have a single drop line.

As I say in my review, do not buy ANY Motorola modem. They are completely unreliable and a total waste of money. If you want a good modem, get an Actiontec GT784WN.

I don't know what you mean by that question. the better question is what mbps speed it can handle. this is a low speed modem, it won't handle speeds greater then 12 mbps. I had to go with the sb5101u. good luck.

Ugh, I was afraid it was something like that. Either technical, or just SPRINT disallowing it so people don't abuse it and use it as their main modem. *sigh* Yes, for the price you would DEFINITELY think it would work. I haven't had any more luck, and I pretty much gave up.

It depends with speed of your megabits of your service. I had century link but then my one year contract was over . then I ask for another one but price of internet changed. So I bought another modem not Motorola. Overall it was good modem .

I have comcast and this modem works fine for me.....but they keep asking me to change it and purchase the newer model which can accept higher speeds. Unless you are paying for a top internet speed from your provider you don't need the upgrade to this modem. This is a DOCSIS 2.0 modem and the newer one is the DOCSIS 3.0 modem....with a higher price. I guess this item is the "older" one but it works well with many providers (I've been told) and it's definately easy to set up. I'd check out both modems and see if the upgrade is something you want or need.

Works for me with Oceanic. The tech said it wasn't listed but she tried to activate it anyway and it worked. My only issue is the speed. I'm paying for 50/5Mbps which I was getting with the modem from Time Warner. With this modem I'm only getting half that rate.

It is 100% compatible with COMCAST, VOIP, internet and TV - crystal clear phone. DOCSIS 3.0. I have never seen anything install so rapidly and fully like real bread and butter. Unless COX is from the MOON and totally different than COMCAST cable ... I think you should experience the same satisfaction. The big trouble is finding this modem available anywhere. The full install and firmware upgrade took a full twenty minutes with COMCAST ... all automatic ... one mouse click.

Odd answer from Comcast since they supplied me with the SBG900 cable modem when I initiated service in the fall of 2008! They probably have a deal with another supplier with either a better cost to them or better specs but it definitely still works and I have been very pleased with the range and reliability.

I am using this exact one now and looking to upgrade. This is a Docsis-2.0. If you have to buy a new one then get a DOCSIS - 3.0

i don't know if this is old or not...mediacom issues the same one. it works great and was easy to set up. mediacom detected it right away. i rebooted the system and was off and running. time warner may have a list of acceptable modems on their website. mediacom has a list on theirs, but i don't know much about this stuff, so i called the tech department. in the end, i just ordered this one which is the exact one i already had from the company.

I ended up buying it because one of my coworkers has the exact same router as me Linksys Gaming Router (Gbit) (WNT330 I think) along with this CM100 modem. It works perfectly and never drops away from the ISP (COX communications). If you have the option to manually choose a DNS server on your Router, try 4.2.2.1 or 4.2.2.2. Those are fast national DNS servers (I think they are Verizon servers, but it should work).

Purchased one, it was the TG862G-NA8 variant (the -NA8 variant was flash updated by the Comcast techs and it was operating at the contracted rate, both uploading & downloading), and it was installed 18-Sep-'15 and as of this writing (23-Sep) is working flawlessly. We did not have a need, today, for the voice aspect, but the data, routing & firewall functions were working without issue.No "gotchas" or exceptions -- the BIOS update took a little bit of time (~10 minutes), but the device rebooted a couple of times, inline with my expectations, and we were on-line.

Hello, FRANKLIN SPRINGER.I have used it with the Internet and DLNA and that last one does not have more of downloading 10Mbps and promotion when in the description is selling like high-speed even of 300Mbps.Try to use it in the USB ports with hard drive of 1TB and also gave the same downloading speed and promotion.The reference it mistakes telephony in the description and I thought it was a servers and SIP for customers only SIP.The truth is the high cost is preferable to buy a Buffalo for the same price, and even less since the end just use wireless Internet for DNLA since it does not do me at that speed.

Yes this works fine with Comcast and Charter (or any cable internet company), but you can't use it with their telephone service (so if you sign up for internet and telephone you have to get a different model). This device is an all in one with included WiFi, which makes it a great small device that covers all your bases.It isn't DOCSIS 3.0, but that doesn't matter since Comcast speeds don't even reach the capacity of DOCSIS 2.0

I don't know if this answers your question, Andy -- but I do SKYPE with my homies back East -- crystal-clear video AND audio -- and I also run daily VOIP tests at this site: whichvoip(dot)com, with excellent test results. MY SB6120 has met every challenge for over a year, faithfully and flawlessly. I'm on COX Cable --20/2 package.

I had no issues with this and windows 8, 8.1 and 7, Mac, iPad, etc, you name it, It worked just fine with it. depending on the area you want to cover you might want to look at one with an external antennas, and I would be sure to get one that's 'dual band' both 5Ghz and 2.4Ghz, and I had no problem with a very compilated network, including 2 additional swtiches after it and a motorola surfboard DOCsis 3.0 modem before it in place of the cable companies little docsis 2.x thing that kept jamming me up. Increased my speeds by 2x for no additional monthly modem rental
