road-runner, just a quick google search and I came up with this. I hope it helps.

Windows Server 2008 (”Longhorn”) Wireless Gotcha

Well, it seems that yesterday’s issue was not hardware or driver related at all (sorry Asus!). Windows Server 2008 (”Longhorn”) does not install wireless networking support by default and you must install it by adding the Wireless Networking feature (details at http://blog.kirupa.com/?p=99). Although I do feel a little stupid (especially after buying a second wireless adapter) it would have been nice if the Network Diagnostics told me that Wireless Networking had to be installed rather than suggesting a hardware/driver issue or a missing TCP/IP protocol.
