The reason this problem happens is because Vista was designed to use a third party connection software rather than a driver based authentication.

For example, my laptop came with Vista, I loaded XP onto it, and the wireless worked fine anywhere. When I reloaded Vista, I encountered the same problem. Some research showed that Vista is looking for a third party software to actually do the connections and authentication (in my case, the Intel Wireless Package software that was originally pre-installed on my laptop).

Installing the XP drivers is one workaround, or you can use the connection software provided by your wireless card/chipset manufacturer.
