Vista 64 bit and WPA?

  danielgent 10:50 29 Jan 2010

Got a strange problem here and I'm going to lay the blame on vista 64 bit. Setup a wifi network that was previously unencrypted to WPA-PSK (TKIP). As WEP is no use anymore, WPA-TKIP is the next step up. I've only ever had problems before with WPA2 (AES) with some versions of XP not letting you put in the right number of characters and etc.
I've connected 3 different XP machines to this WPA network with different manufacturers of wifi cards/dongles.
The Vista 64 machine just won't connect. Gives the usual "connecting it taking longer than expected" error. tried 3 different wifi dongles, including 2 that work on the XP computers.
Any ideas or pointers for whats going wrong? Help would be much appreciated. The PC connected fine before encryption. DHCP is setup and I can't think of anything else to test. Its Vista 64 bit RC1.

Much thanks as I'm really stuck,
Dan Gent
