5.0 out of 5 stars PERFECTION, for Docsis 3.0 Installations, October 24, 2009

This review is from: Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem (Personal Computers)

I was renting a modem from Comcast for $4 per month which really was horrible. The modem would crash, reboot, not work, etc... I spoke to some Comcast tech's on Twitter and they recommended I go and buy this modem since it was not yet being distributed by them in my area. Voila, off to Amazon I went.

I purchased the modem, it arrived the next day. I turned everything off....router, computer, etc. The setup was as follows:

A. Plug cable into new modem.
B. Plug ethernet cable from modem to your computer (first time only).
C. Power up modem.
D. Power up computer.
E. For Comcast - Web page comes up that allows you to change your modem.
F. Enter some details....ie. your account number, etc.
G. DONE....shutdown modem, and plug ethernet cable to Router.
H. Enjoy DOCSIS 3.0

I have had this thing for a few weeks now and it works perfectly well on a daily basis. We are actually getting what we pay for...which was not the case with the old junk that comcast provided. We are getting about 60mbps down and 12mbps up...on a good day.

Motorola has an excellent modem again..

4.0 out of 5 stars The Game player review, August 6, 2009

Joseph Alegre "Joe Review" (Chicago, IL) - See all my reviews

This review is from: Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem (Personal Computers)

I bought this modem the other day because I felt my old SB5101 modem was not optimized for speed. I have a regular DOCSIS 2.0 service through Comcast. The modem made a huge impression on me after it was installed. The download and upload increased around 20 percent. The amazing thing is that this modem squeeze extra bandwidth out of your existing service (weather you have a standard basic megabyte connection or the newer DOCSIS 3.0 service high speed connection). The noticeable difference was the latency speed of the connection. When I click on a link on a web page, the page loads up as soon as the link is clicked. My old SB5101 modem would take a few extra milliseconds to load. What does this mean? If you play video games like Halo 3 via X-box or Call of duty, you will have a reaction time advantage against your competition. The clear negative of this product is that it takes longer to boot-up. If you power cycle the modem or if your internet service provider resets the modem, it will take two minutes to restart. It will take Comcast longer to recognize the modem when you call in to give the Mac address because when they reset the modem remotely, it will take two minutes for the modem to initialize. Once it is online it performs flawlessly. Anyone that buys this modem will benefit from the extra tweaks it has regardless if the are using a basic or super high speed internet service.

1.0 out of 5 stars May have compatibility issues with Comcast, January 11, 2011

Like another recent reviewer, this Docsis 3.0 cable modem may not work with Comcast, even though SB6120 is listed as one of the "approved cable modem 3.0" on Comcast's website. Google "sb6120 comcast problem" and you'll find more details.

The comcast technican/installer was at my house and spent 45 minutes trying to make it work. The SB6120 seemed to be having problem syncing with the server and kept getting reset continuously. The technician was on the phone with the support team, and at the end he said it was defective. He put in a comcast supplied 2.0 RCA modem and it worked. Amazon shipped me a different replacement SB6120 4 days later, and the replacement showed the exact same symtom and would continously reset and wouldn't sync. The comcast phone support agent told me they are able to see the device but somehow it still didn't work properly... We swapped the comcast RCA modem in and it worked right away again.

Bottom line is that there appears to be some compatibility issues with Comcast & SB6120, at least for some. I tried two different ones and they both had the same issues. Again, google "sb6120 comcast problem", do your research and make the decision yourself. Unless the batch of SB6120 from amazon is defective, there probably are some firmware or compatbility issues for some of the modems, even though Comcast lists SB6120 as an approved modem...maybe just hit or miss.

Having tried two of these, I am giving up and am now paying more to get a zoom 5341 3.0 modem instead. Good luck and thanks for reading. Hope this helps.

Update: ZOOM 5341 has been running strong after 6 months of use. I have not had a single issue with it and it has been very stable and very speedy(upload/download).
