I need to know how to share files between my 2 PC's that are both on the same network. My setup is 1 pc with Vista Home Premium and 1 pc (media centre) with XP Pro, neither PC is hardwired into the Router. The router is plugged into the cable internet connection directly and then the 2 pc's are connected via WiFi. I have a D Link DI 524 Router, D Link G122 USB on the Vista PC and a D Link WUA 1340 USB on the Media centre.
