Does What I Need and Stays Connected
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Thus modem was bought specifically to replace a dying older surfboard modem at home, and it does exactly what we need: connect cable Internet to our router.

Good product works as suspected
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This is great for getting rid of charges that some cable companies charge you for modem rental,. Some of which can be 6 or 7 dollars a month, it will pay for itself within a year, and you get to keep the savings.

Not a bad modem, but not great either.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Have to reset it more often than necessary. But otherwise, works pretty good. Price was ok. Affordable. Not a bad modem, just not a really great one.

Very Good Modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I have not had any issues. I kept losing my internet connection so I was a little concerned as to whether I needed a modem or another router. Since the modem was many, many years old I decided to replace it.

Xfinity Router
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.If you have to have Xfinity/Cascast ISP in your area over Frontier, then this will be a good option to not have to pay to rent a modem from them. You will easily make-up the money spent on the router by not paying the rental fees in less than a year.

Better than renting one ...
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.With what the cable company charges to rent one, I figure I'm about break-even within the year. Since it should last longer than that, I'll end up saving at least as much as I spent and then sone.

Assigned to someone else out of the box!!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Someone must have installed this modem and then returned it. It would not allow me to assign it to my internet provider. Had to take it back. Best Buy switched it out without an issue, but they were out of stock. Upgraded to a different motorola.

no problems yet
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.the product was a little bit expensive but I bought it so that I wouldn't have to pay the cable company the money so in the long run it will pay off for me and the cable company won't get my money

Works with Comcast Service
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Once I figured out how to use it, this modem has worked great. The initial trick was you had to plug everything in, in the right order. Works with Comcast/xfinity service and cheaper than renting.

Lots of Wi-Fi power
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.We had a generic wi-Fi modem previously which required an extender because our house is on the bigger side. With this modem we no longer need the extender because the range and strength are great.

Works great but took time to set up.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I have had no issues since I got it running. Setup was complicated with having a new internet carrier and uncertainty of where the carrier enters the house so it was hard to test the modem until everything was simultaniously resolved.

||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This modems works as advertised. It will deliver twice the data rate that I needed when purchased so it will be good in the future. It is not a modem/router which is exactly whaet I wanted.

Great signal!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I love this product! I can get wifi in any room in my house even outside, my previous router would buffer and have a choppy signal in rooms outside of the device.
