I am using WMP54GS wireless NIC on Win Xp x64. It works fine on regular winxp but not for x64. I have the approriate Broadcom x64 drivers that reportedly work with most people. I can see the access point with full strength on windows wireless utility and have my WEP setup. When I goto connect it hangs and just doesnt connect. It doesnt give me an error message either and does not freeze up, the connecting window just eventually goes away.
