Ok here is a cheap way to get net upstairs to 4 PC's then. Use the one with the wireless adapter as an ICS rig with a hub connected to it's ethernet port. Basically making itself an access point. The rig with the wireless adapter, is it your folding rig? Yes, I am probably confusing you with 4 different ways to do this. @ d44ve Range extender would work the best with this! Heh.
