Works well in our 2600 sq ft ft home. We used to have dropped signal with our previous router/modem. Have yet to have any issues with our connections after getting this mode.
I was not sure about "cutting the cord" from Comcast as I was not certain I could do everything myself. First step was to buy the Nighthawk AC1900 after reading the reviews and I am happy to say I am now cable free! I was amazed at how easy the Nighthawk AC1900 was to install. Excellent coverage in my three level home!
Super easy to activate through app, never thought the activation of modem/ router can be that easy with provider when using your own modem/router. Speed is good and coverage is excellent throughout home, no need for wifi extender any more.
