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..
I do not have screaming fast internet, although my computer is pretty bleeding fast. I can't afford that kind of cost for a monthly subscription, because it is a constant and forever drain of a lot of money, and I don't earn that much money where I can do that.
I am located in the Phoenix, Arizona area, and have the $40/month Preferred internet package. My downstream bandwidth varies a lot by the time of day, it ranges between 13Mbps all the way up to about 23Mbps when almost everyone else is in bed sleeping.
My upstream bandwidth is capped real low, as with most consumer internet packages, so it hardly varies at all. It's almost always the same, at about 1Mbps.
If you want an accurate test of your internet bandwidth, do not use the main bandwidth testing sites. Their tests are way too short in duration and give you an extremely exaggerated notion of your top speeds. Go to testmy dot net and use the largest size tests they will allow you to.
Before purchasing this modem from an unnamed extremely large local retailer, I had read lots and lots of reviews saying that this modem dramatically improved the speed of relatively slow connections. I tested my bandwidth both before and after very thoroughly, both upstream and down.Read more ›
At first, I thought I'd just buy what I already had: a Motorola SURFboard SB5120 DOCSIS 2.0. So glad I didn't! Instead I shelled out a bit more money and picked up the Motorola SB6120 SURFboard DOCSIS 3.0.
I read the reviews on Amazon prior to purchase, but was skeptical about the claims of increased speed with this modem. It didn't make sense to me, as I'm paying for an internet package with certain limitations on download/upload speed. It only seemed logical that better technology wouldn't be able to surpass limitations the package I pay for has in place. But in the end, what drove me to choose the SB6120 over the SB5120 was the idea of future-proofing; if I'm paying for it, I might as well get the better option.
Once I had the SB6120 running as my own modem, however, I was pleasantly surprised. My Comcast Internet package deal, which has not changed throughout my recent modem replacement, is as follows: Performance 12 Mbps download/2 Mbps upload with powerboost. Also, my area supports DOCSIS 3.0, so my package, utilizing a DOCSIS 3.0 modem, would automatically increase to 15/3 with powerboost. I took some speed tests (speedtest.net) before and after the new modem, and here's what I got on average:

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).Read more ›
