Modem

Good router if you have a 25mbps connection
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.If you have a internet connection of 50mbps or higher, this router is going to act up on you as this will throttle the speed to a lower value. Until i had a 25mbps connection i had no issues and it worked like a charm. Setup was easy. But when i upgraded my internet to 50mbps it started throttling the speed and i was not getting the full 50mbps when routed the data through this router. I would have given 5 stars if i did not face this issue.

Works very well and is saving me money
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This modem works very well and is saving me money as opposed to renting the equipment. I suspect that it may even work better than the rental version.

Works Great!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I was a little concerned as the price was too good to believe. But as other reviews stated, it works like a charm. Why spend more when this suffices?

Adorable and Practical
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This tiny little modem does exactly what it's supposed to, and is perfectly priced. Way cheaper to have your own modem then to lease out from Xfinity.

Very good modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Comcast updated their system and I had to change my modem to one that works with DOCSIS 3.0 . I had problems with Motorola before and have to confess that I hesitated to buy another one again. The first one I had to return and I've exchanged to the Surfboard Arrais one. So much better! I got the speed of 57Mbps with a AC model router. My internet is flying now! Totally recommend it!

Basic Modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Basic Modem, nothing more nothing less. Alil overpriced, but if you can get it on the cheap its worth it. at $70 I'd reccomend throwing a few extra dollars and getting the newer version

Great Replacement for Comcast Modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I was tired of paying the pig (Comcast) and figured why not save $10 a month and replace their modem. This was simple to install and works great.

Gets the job done
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Seems to be working fine for my needs. I had some issues on initial set-up with it essentially rebooting itself every 5 minutes, but after a power cycle it seems to work fine. Comcast technician said he had bad experiences with this brand in the past though. I have it connected to a Belkin Router and I have Xfinity BLAST internet @150mps. Generally there have been 2-3 people using the internet and 5-6 devices connected online at any given time. Again, no issues. No need to pay any more for a more expensive modem unless for a large household/business.

No need to lease a modem from cable company
