Linksys WMP54GS in Vista RTM

I have this card installed on Dell Optiplex, and it was working fine with XP
and Vista Beta 2. However, on a clean install of RTM, I cannot discover the
home network. Instead I am "piggybacking" off of some poor dumb schmuck in
the neighborhood that has not set up security on their home network My
laptop using RTM discovers half a dozen other wireless networks and since I
set up WPA/TKIP with the proper SSId and pass phrase it logs into my home
network. Not so the Optiplex, even though I have set the SSID and WPA/TKIP
pass phrase several times. All the Optiplex finds is this one little
unsecure network. I attempted to install the download package from Linksys,
but the Broadcom drivers in Vista are newer and Vista typically refuses to
install the download. If forced, the download drivers don't change the final
result ... only one wireless network discovered, and it's the wrong one.

Has anyone encountered and resolved this?
