This is a great modem!,
Verified Purchase(What's this?)
This review is from: Motorola SB6121 DOCSIS 3.0 Cable Modem in Non-Retail Packaging (Brown Box) (Personal Computers)
I began to suspect that something was wrong with my network gear when my Skype calls kept failing. I checked my internet download/upload speeds and found them at only 8mbps. With a bit of Googling, I realized that the cable modem I was renting (for $7.50 a month) from Comcast was nine years old.
This modem was very high on the list of Comcast-approved modems and the online reviews were very good.
I ordered the modem (great price;) got it in a couple of days(great service,)plugged it in (simple as can be,) and called Comcast to let them know to update their settings to the new modem and BAM -- 35mbps download speed. This is a very, VERY good modem.
