We bought it from "Fry's Electronics" in Plao Alto and used it for 10 months. This type was certified for Xfinity from Comcast and much cheaper than renting one with $10/month at Xfinity. Top easy to use it. Just plug it to the swith to keep the signal on.Your laptop can easily find the WIFI signal which User & Passward were printed at the bottom of the equipment.
