hi i dont really understand how networks work or rather I thought i did before this just wouldn't work. I have one computer in my study connected to a Bt Homehub router and a computer in my bedroom with a router attached to it.. I want them to connect, i have tried a number of different things.. the study computer is running on xp and my bedroom computer is on windows 7 i dont know if that effects anything, i really have no clue what im doing please spell it out for me
