Excellent modem for my needs.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this, my second Motorola modem, to upgrade to DOCSIS 3.0 . I was very pleased with my old Motorola modem, which prompted me to buy another. I am very pleased with my purchase.

Adequate Modem for the Price
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My cable company required me to buy a new cable modem for their "faster" speeds and this was the best priced option at the store. It works about as well as the old modem (which I liked well enough) so no complaints from me!

Good value for price
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought it so I would not have to rent Comcast's. Good value for the money. Only one Ethernet connection, but if you are using wi-Fi technology...you should be ok. No problems except Comcast connection from time to time...

Modem OK
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I myself can't see any difference in the speed of my internet..maybe just be me. It is still slow not sure by purchasing this item if it was worth the cost. Haven't tried streaming from the internet to my smart tv yet.

Works Well, Durable, Saves Money
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This modem has lasted over two years. Considering what I'm saving by not paying Xfinity $10 a month to rent a modem, it has more than paid for itself.

nice upgrade
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.We were having tons of trouble with the device provided by our satellite company and wanted something more modern. This fit the bill and my husband had it up and running before I even missed out on internet access.

Great modem to replace Comcast modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This is a great way to escape the $8/month fee Comcast charges to rent their equipment. In less then a year the modem has bought itself and by spending the extra for the warranty it is guaranteed for two years.

compatible with Comcast
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this when I moved where only Comcast service was available. Used together with a Belkin router for 1.5 years and the speed became quite slow and we changed to a netgear.
