SO easy to set up

Purchased this so I could return my rental one to Xfinity. $14/mo for the next 2 years is MUCH more than the total price of this (with a coupon too!). Very happy with this investment. Super easy to set up. I had zero issues.

Lenna S.

I love this product, I would recommend it to family and friends 1000%

Marie E.

easy to set up and start using

Maksym K.
reliable 2 years and counting

No interruptions in work. Reliable.

Julia S.

Motorola modem is working perfectly! Very easy setup almost like plug and play. It only took about 15 minutes with my internet Ap and no issues with the Motorola modem linking up with my Netgear Nighthawk router in a separate room. Liked not having to deal with a dumb computer or waiting for a tech to answer a que.
