Disable validating identity on wireless
Screenshots are taken from Professional version thus may slightly differ from other versions (e.g.
Home Edition, etc.): You have now succesfully configured Windows XP to connect to eduroam network.
I'd start by reviewing the event logs on your IAS server for reasoning as to why it's not authenticating your client.
I added the AP as a client with and have tried using both RADIUS Standard and Cisco as the RADIUS type.
The weird part is that I was using WPA TKIP with the passphrase and it was working fine.
I moved the selection tab to WPA2 only and keep the rest the same and no luck. Ok so I setup the router to only transmit wireless N and to use WPA2 only.
 = If the eduroam network does not show up, click on Refresh network list.
If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
