I've had the same problem going from Windows Mobile 6.0 to 6.1 to 6.5 on different devices.
At my university, Stockholms Universitet we have a wireless network shared with KTH, the Royal Institute of Technology. This network serves 15.000+ students (not all are going to connect to it obviously, but all have access if they need).
The problem is that a Windows Mobile device cannot access the protected/automatically connecting versions of this network "KTHOPEN-WPA" or "eduroam". Windows Mobile users are forced to connect to a open version and log in using a web browser. If you really quickly want to check your schedule or something, this is of course far from ideal. Other devices like Symbian, iPhone etc can connect with a minimum of effort.
I'm not an expert on WPA or network authentication but what I've worked out is that the network uses WPA2 Enterprise with PEAP and and authentication using a certifice. I'll post the instructions needed for connecting to it using a standard Windows XP PC (Windows 7 works simply entering username and password!)
These instructions can be found here:

Instructions for standard microsoft driver
- Click on the wireless network icon in the bottom right corner of your screen. A dialog opens.
- Click the "Properties" button. A Properties dialog opens.
- Switch to the "Wireless Networks" tab.
- Click "Add...". A new dialog opens.
- Enter the following settings:
- Network name (SSID): eduroam
- Network Authentication: WPA2 (or WPA if there's no WPA2 in the list)
- Data encryption: AES (if possible)
- Switch to the Authentication tab.
- Select "Protected EAP (PEAP)" in the "EAP type" box.
- Uncheck "Authenticate as computer ...".
- Click Properties. Another dialog opens.
- Find "GTE CyberTrust Global Root" in the list of certificate authorities and check the box next to it.
- Click the "Configure..." button. Uncheck "Automatically use my Windows logon ..." and click OK.
- Click OK in the rest of the dialog boxes to close them.
- Wait a little and a balloon will pop up in the bottom right corner saying "Click here to select a certificate or other ...". Click on the balloon. A dialog will open.
- Enter your username (e.g. nisse@kth.se) and the network secret you retreived from here . Leave the domain field empty. Click OK.
- You have now configured eduroam.
If anyone against all odds has any suggestions on how to get this to work I'd be amazed. But if this could be put on a to-do list for Windows Mobile 7 I'd be happy enough.
