Fastest Modem I've ever owned! Thee Best!
Product works great. Have had checks done with my provider (Cox) and they show a very good upload and download speed. Setup was easy. I'm very satisfied.
Comast increased the renting charges on the RCA docsis 2.0 modem so I decided to go for this one. Setting it up was easy and I called Motorola support just to make sure that the MAC id was right. After that I got it registered with comcast and it's been working great ever since. I see much faster download/upload speeds than I'm subscribed to. Highly recommended!
Great Cable Modem5/19/2011
The wireless range on this thing is amazing, no problems anywhere in the house and I set it to 75% power even. The setup is simple and fast. The connection is quick even with multiple machines running on it. It's a little pricey, but 5 stars everywhere else.
Great lightning fast modem!!!12/7/2010
After years of renting a modem from Comcast, we finally decided to purchase one. I was blown away by the upload speeds. I upload lots of full size photos to a photography website, and previously, I set them up to upload before going to bed at night, hoping that they would be completed in the morning. After connecting this new high speed modem, I saw speeds of up to 990 kbps, and my photos are uploaded in a fraction of the time it previously took. I thought I had high speed internet before, but this was a whole new experience. I'd highly recommend it for anyone who uploads or downloads a lot of information on a regular basis!
Excellent cable modem11/15/2010
This is an excellent product and provides a significant performance increase over the Motorola DOCSIS 2.0 model with no additional cable provider costs.
Great Modem! Great Price!10/15/2010
With free shipping, I received the modem very quickly. Buy.com had the best price I could find. The modem works very well. I would recommend it and Buy.com to others.
My subscription speed says up to 16 mbps with this modem I am getting an average of 20 mbps with Charter Internet. Have had no problems easy to set up with linksys router as well.
I love it! I was previously using a DOCSIS 1.1 modem made by Linksys which was several years old. When I heard Comcast was upgrading to DOCSIS 3, I purchased the 6120. Hookup was simple, but it does require a quick call to Comcast with the modem info and then your normally good to go. I was actually a little early and the DOCSIS 3 service wasn't quite avaialable yet so I temporarily went back to the old modem. I kept the new one in the box for about a month and tried it again. WOW! I was blown away! According to SPEEDTEST.NET, my download speed went from 7mb to 39mb. 39! 39! I am getting 8mb on the upload speed.
Fantastically Easy Setup5/3/2010
I am technologically challenged - this was so easy to setup and understand - 15 minutes!
It works. It's fast. The end.
I have the 15mps down and 3mps up with bursts service provided by ComCast using an old cable modem with 1.0 ver of DOCSYS. Once I installed the modem and called Comcast to give them the MAC address I was up and running in 15 min total. I am now constantly getting 20mps down and 5.0mps up. Couldn't be happier

ON THE CUTTING EDGE6/28/2009
I had a SB5100 modem and upgraded to this with Cox Cable. They will not finish upgrading to DOCSIS 3.0 for about 6 months from what the technician said. I just unplugged the old one and plugged the new one in and let it initialize. I still had to call Cox and give them the addresses of the modem though. That took more time than anything. Mainly because the technician was asking me about the modem and where I got it. He said Cox had just put this one on their supported list (I already checked that). After we got it running (WOW) he wanted me to go to speakeasy and run a test from the Dallas and Chicago servers to see what it did. It downloaded 27,000Kbps and uploaded 5100+Kbps. He said he had heard this modem was coming out but he didn't think it had yet. He was asking me more questions than I was asking him. I gave him all the information about Buy.com and what I paid for it and he was going to get one the next day. He said my speed should slowly increase as Cox upgrades to 3.0 but that I am ready.
Appears to work great.
