Vista - Wireless LAN on Vista.

Ralink has x64 drivers available for their chipsets the various
manufacturers using this chipset can be found at http://ralink.rapla.net/
and the divers at http://www.ralink.com.tw/supp-1.htm. Broadcom chipsets
also have drivers for x64 used by other manufacturers. As a side note in
Vista x64 the Ralink and Broadcom drivers install out of the box for PCI
wireless cards using these chipsets.

The above is a copy of what I posted in the x64 newsgroup but it also
applies to Vista at this time. I don't have RC1 yet but PRC1 x86 the
wireless PCI card drivers install during installation also. To determine
what chipset the wireless card is using requires reading the name on the
chip on the wireless card. As an example Belkin uses multiple chipsets as do
other manufacturers. I got lucky because the Belkin wireless card that I
have has a broadcom chipset. My main system has a Zonet wireless card that I
bought because it had the Ralink chipset for use with x64.
