This modem is not only on their approved list, ithas a three star rating, which, according to Comcast, is "the highest and most thoroughlevel of testing." When the cable installer got here (I got a new line installed), he said thatthis modem was NOT on the Comcast list. Page 1 of 4
  2. 2. Since I still had my DSL line working, I showed him that not only did Comcast approve themodem but that Comcast thoroughly tested it. He had to call the "office" to activate theinternet service. The "office" didnt want to set up internet service for this modem; the"office" stated that this wasnt an approved modem. Well, he recalled the "office" and gotsomeone else and they set up the service.Ive been happy ever since. Im supposed to get up to 20 Mbps download and 4 Mbpsupload. My computers are connected wirelessly. Speednet states that I am getting 20 to 25Mbps downloads and the upload speed is between 3 and 3.5 Mbps. Ive gotten similarvalues with speakeasy and other internet speed testing sites. I have a lot of devicesconnected: three computers (wireless), two TVs (one wired, one wireless), three differentgame consoles (connected to the wired TV), two Nintendo 3DS (wireless), one printer(wireless), and an iPod Touch (wireless). At times all of these devices are running at thesame time - the computers are streaming You Tube videos, one of the TVs is streamingNetflix, etc. The modem handles all of it effortlessly. Im really pleased with this modem.I find this to be the best modem for Comcast.Works and Easy Comcast Self Hookup, December 14, 2011By RightReviewNow12/14/2011 Just received the Motorola SB6121 SURFboard DOCSIS 3.0 Cable Modemtoday. Followed the self-install instructions included with the modem, using Comcastinternet, and a Medialink Wireless N router, and was up and running in 20 minutes. Note;also used a Windows OS laptop for the setup, with Internet Explorer.Heres how my setup went. Disconnect your old modem. Connect the SB6121 modem toyour internet coaxle cable. Now connect the ethernet cable to both the SB6121 modem andyour computer. Power up the SB6121 modem and wait for all lights to stop flashing (musthave solid lights), then power up your computer. Now, open Internet Explorer browser andwait for the Xfinity screen to automatically show up on your Internet Explorers screen.Enter your Comcast account number and the phone number associated with your Comcastaccount on the screen, where asked, and press next. The SB6121 modem will then beautomatically identified and recognized.Press next to accept the Motorola SB6121 cable modem, then wait a few minutes for thenext screen to show up while the information is being processed, then press finished. 3screens total. Disconnect the ethernet cable from your computer and connect it to yourrouter. Now, power both the SB6121 and your router off and wait 10 seconds.Now, power the SB6121 modem on and wait for all the lights to show themselves. Now,power on your router. You should be able to go online wirelessly. Literally that simple. TheComcast Xfinity self-install screens did not ask me for a MAC address or a serial number.Total time - about 20 minutes to remove the old modem and install the SB6121. Best part,no having to call tech support and no frustration!I was quite surprised at how easy the SB6121 was to install, as it seems like Im one ofthose guys who takes 2-3 hours to hook anything up. Seems like theres always that onething I didnt know, or think, about, and Im usually on the phone with tech support for awhile having a lackluster time. I replaced an old Comcast RCA modem which I had noproblems with, but was tired of renting from Comcast at $84 per year. The SB6121 will pay Page 2 of 4

It is now on their list ofapproved modems and it works great. Im paying for 15 Mbs and hitting 20 on a regularbasis on Great product totally worth it. Also my 20 Mbs is over wirelesshavent tried it wired, it may be even faster.Fast speeds and reliable Internet with Comcast, January 7, 2012By RomyISP: ComcastComcast Internet Package: Performance ( 15 Mbps )Comcast provided modem: Their "latest DOCSIS 3.0 Arris" modemRouter: Linksys E4200 v1The reason why I bought this modem was simple...why pay $7/month to rent a modemwhen I can buy one myself, with potentially better specs, and cost savings 10 months out. Ifound good reviews for this modem and figured why not, especially since shows that this specific modem is signed off as supportedby Comcast, along with their highest, 3-star rating.I cant be certain that the new Motorola modem is buying me speed/reliability over the Arrismodem, but I know that my wife and I have been running our computers and gameconsoles without a hitch. With the Arris modem, we found the internet to slow down severaltimes a week requiring modem reboots, but maybe were just getting lucky. But hey,possible positives are a good thing right?Im paying for Comcasts performance package which claims speeds of 15 Mbps down. Withthe Arris I was seeing speeds around ~17-25 Mbps down. With the Motorola SB6121 Imseeing 20-25 Mbps down ( both much higher than expected ).Ive seen slow uploadswith both modems, but I think thats a Comcast thing. ( random: I previously had FiOS25/25 and was getting 30/25. those were the good ol days )If youre using this with Comcast, remember that youre going to have to contact customerservice and get them to send a signal to your new modem in order for it to work - dontexpect it to be plug-n-play.Great Modem - Perfect with Comcast, December 28, 2011By T. KendallThis is much better than paying Comcast $7 a month to "rent" their modem. It was 100%Plug and Play instead of "Plug and Pray", as many are. Works great and is so much faster Page 3 of 4
