I am considering setting up a wired network for part of my house, but because of the layout of my house, I am unable to connect the wired part directly to the wireless router/cable modem. I'd love to be able to cable the whole house, but it be far to expensive to do it correctly.
My question is: If I connect two or three computers via gigabit Ethernet, will I be throttling the connection speed by tunneling that connection through a single wireless adapter? Would the connection be unusable for HD content stream if two of of the PCs were streaming HD video? (And possibly a third.)
