A:Answer We just purchased this. Our router/modem is from Comcast (Xfinity). I can't say for certain it will work with what you have, but I don't see why not. This is a wireless setup, so there are no wires connecting it to your internet provider's router and modem. It can be challenging to set up, but once it is set up, it has worked well. Home is about 3000 square feet.
You could also consider the Netgear Orbi or Eero's second-generation Wi-Fi system, which are a bit cheaper.
