Home Network Hart

My home network is made up of a Xbox, a nook color, an I pad,  two Chromebooks  a desktop computer wired in and a laptop that is wired in.  The Internet get sent though from a motem router combination sending WiFi thought my house. They get it from the coax cable coming up and though the wall.  You have a coax cable if you have Comcast internet.  Also the router is connected to the laptop and desktop through the Cat-5 cable.
