I think we had same issue at work.
(hard to tell for sure)
If I remember, INSTEAD of clicking "find avail wifi...?",
RIGHT_CLICK the aforementioned "find avail wifi...?" box
and choose "find wifi net...?
I can't be certain until tomorrow am.
(took 2 programmers, 1 EE, and a dog two days to figure it out)
It's a stupid permissions based...Vista is extremely Unix like, in it's root permissions, but the fucked it up in their menus.
(Also make sure the wifi button is to the "on" position (yeah, yeah,...just make sure))
if still stuck, I'll see if I can recreate.
