would it matter if i hooked up a wireless network where the router and the motem were in one room, and say, in the living room i hooked up the wii which would be about 25 feet away?  would line on site be an issue or does walls and objects really matter on wireless?  also, could i just leave my two computers hooked up through cables, and then just have the wii hooked up wirelessly?
