    Provides excellent coverage for my two story house with a partial basement. The base unit is in the basement and the two satellites are on the second floor in two bedrooms. I paired this with a ARRIS - SURFboard S33 32 x 8 DOCSIS 3.1 Multi-Gig Cable Modem with 2.5 Gbps Ethernet Port - White which I purchased as the same time as the this WiFi router.

    Fixed out problem. Had to replace a somewhat new router due to not supporting the full 1Gb service. This did the trick and now we are humming along.

    I moved from a xfinity wifi modem to this one when i increased my internet speed to 600 mbps. I have a nighthawk wifi router and it does require a modem. And this one really solved the purpose. Satisfied
