Hi, I need help setting up a home network. I have a PC running Windows 7 and an Xbox360 both of which are connected to a router and a dsl connection. I recently got a second internet connection installed downstairs in the house, I want to use this second connection to be able to share my media(which is stored on my PC) across the whole house(I also want my PC on this network), which are 3 rooms, two with TV's (living room, lounge) and 1 with a laptop(bedroom). What equipment do I need and how would i go about this efficiently? Any help would be greatly appreciated.
