OK, the driver called "UI Package and Driver (Support XP/Vista/Win7)11222010/1/2514684k
"
found
here should work for you.
Since it doesn'ｔ, I'd like to recap:
Does the driver install? If not, I'm stuck.
If you can't connect from your room but you can connect from the bar, there's a signal issue. Can you move and/or rotate the wireless hub, even if only a small amount? Does it make any difference? If not, continue.
Would you be comfortable downloading software that will tell you the signal strength of all sites in the area, in case you need to change wireless channel?
