I want to run ethernet to my son's room so his Xbox doesnt lag due to intermittent WiFi. He is on the top floor and the router is in the downstairs study and his WiFi reception is poor. His room has a phone jack with Cat5 wires and I have read they can be converted to ethernet. Can someone provide more details of how I can do that? Change out the receptacle in the wall jack to start right? What does the other end.of the wire connect to? The router?
