Good device for price
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I had no issues with this device, I did, however, have issues with setup and Comcast Xfinity, even though this is a device clearly listed as a 3.0 modem that is compatible with their services. I had to do several restarts with an online assistant to get it to work. Just be wary - this may be more of a Comcast thing than an issue with the device.

Highly impressive performance gain
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The product improved my internet speed tremendously. I upgraded to a 20Mbps Comcast service simply because I thought I didn't have fast-enough internet. Comcast sold me the connection, but things didn't get better. An employee at Best Buy helped me out and picked this modem and an N900 router. Ever since then, I've actually downgraded to a slower Internet speed and had better performance than my old modem/router on the 20Mbps Internet. Highly recommend!

As advertised
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought because my old linksys died. It performs well , have had only 1 or 2 signal drops compared to a weekly issue with my last one. Believe it is an ISP issue with a weak signal, not the modem's fault. I would recommend this to anyone.

Don't buy this for use with Comcast
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this modem on 20 Jan 2012 and this was a great modem up until 2 days ago when Comcast updated the firmware. There have been untold amounts of disconnects which has basically made any kind of internet activity useless. When I am connected, I get at steady 25M Download and 3M Upload speeds, but it only lasts for about 20 minutes. When the modem gets disconnected it lasts for about 20 minutes... It is extremely annoying and I am about to return this modem.

Not right for phone service also
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this to replace my cable modem from Comcast that I'm renting. Unfortunetly I also have phone service from Comcast that goes through my cable modem box. This cable modem does not support both internet and telephone and so it's useless to me and I will have to return it. I spent 15 minutes in the store talking with the sales person and he never mentioned the lack of telephone support. I just got off the phone with Best Buy and they said they do not sell a cable modem that supports both and I need to keep renting. I guess I'm in a very unique position.
