Have you considered using an older router to create a wireless bridge. 
I've used dd-wrt firmware and ASUS WRT Merlin firmware so that I can 
connect a computer via ethernet to the wireless router which the 
communicates via WiFi to the main router.

Another option might be MoCA, if you've got coax cable in both the main 
router's location and the remote computer's location. With MoCA, you'll 
get a physical connection capable of up to 2.5 Gbps.
