Wireless connection validating identity
I can't provide a screen shot to illustrate how to do that because I don't know if you are using the built-in Windows Wireless Zero Config, or a vendor specific utility for your unnamed Wi Fi card.
If that does not help, then consider uninstalling the Wi Fi netcard.
WPA2 is supported as i can connect to WPA2 personal APs. During the connection it flashes that it "connected" for a second then goes to "Validating Identity" which it eventually timesout on.
I am using the Windows Wireless Connection Manager. On a couple of occasions I've seen that particular AP (don't know what firmware) suddenly stop attempting to authnenticate clients (it never sends any RADIUS requests) and power-cycling the AP "fixes" the issue.
I suspect a firmware upgrade probably fixes that behaviour. If you want to accept both computer credentials and user credentials you'll need to name both "Domain Comptuers" and "Domain Users" in your policy.
By default, XP will re-authenticate with the user credential after the user logs-on (there is no way to do computer-only with XP, I believe).
If your network is Encrypted go on to step 6 otherwise Click ok and try to connect to your network again.
At the top of the screen, where it says, Choose a wireless network, I get an [endless] Validating identity.
Home Edition, etc.): You have now succesfully configured Windows XP to connect to eduroam network.
In order to connect to eduroam network in future, simply bring up Wireless Network Connection window by double-clicking its icon in the tray bar , select eduroam network and click on Connect.
The below guide has been tested on MS Windows XP Professional and is based on Windows' default wireless configuration tool (Wireless Zero Configuration).
Screenshots are taken from Professional version thus may slightly differ from other versions (e.g.
