Instead of moving the computer, have you considered powerline adapters?
My husband had 3 computers in the basement - all desktops. At one point I used a linksys wireless adapter but the speed was slow.
I purchased 2 of these:[ATTACH]32070[/ATTACH]
One is plugged into a wall outlet and attached by a short cable to the router. The other is plugged in near his basement computer desk and uses a cable attached to his computer. When he had 2 computers that he used online, I attached a switch to the powerline adapter then I was able to run a cable to each computer.
Currently he only has his Win 7 computer online. I've been using this setup for about 9 or 10 years.
