from 130 Mb/s to 6.5 . I hooked up an access point halfway between the
wifi router and the comp (about 60 ft from router to shop comp) with no
improvement . The AP is a Cisco VEN601-ATÂ* originally from an AT&T
U-verse network , but the link and paired lights both come on so I
believe it's working . Is this drop in transfer rate normal ? Caused by
distance ? Maybe the inexpensive wifi card I put in the computer ?

Sounds like the Heisenberg uncertainty principle from quantum physics,
just looking at something effects it and you can't measure it. Or a
catch 22. By that I mean you say that as soon as you transfer something,
the rate drops. But how can there be a rate, without transfering something?
Aside from the philosophical, to diagnose the problem,
I'd drag the PC to the house, where it can talk to the router directly
like the other PCs and see what happens. Sounds like it could be an
issue with the card.
