The Nighthawk app worked incredible and simplified the set up of the modem/router combo. Paired with the simplicity of the Comcast Xfinity app on my iPhone I was able to complete the set up in less than 30 minutes. It would have been less than 15 minutes but I had some hiccups with the Xfinity service.
I love having the modem/router combo. Set up was super easy! If I can do it anyone can do it. Our WiFi is working incredibly well bc we finally asked and got expert advice for our particular home. Highly recommend!
