Hi experts,
I have just set up an Instant cluster with AD authentication in customer. I set up the RADIUS role in the Windows Server, configured the RADIUS client and so on. The authentication method is PEAP. After that, tried to connect to the network from my laptop with Windows 10 and from my iPhone and was successful.
I tried to connect to the network from a laptop with Windows 7 and fail. I thought the reason was the Windows version was old, but after trying the connection from another laptop with Windows 10 the authentication failed too. I checked the wireless driver and it seemed to be updated. After doing some tests, I realized the authentication is successful in some machines while it fails in others.
Does the Windows version have to do with this? How can I troubleshoot this? From the RADIUS server side? Is there any debug commands to see the AP side?
Edit: When I said the authentication failed in some machines I meant in some of them I clicked on the WLAN name to connect but the cursor kept spinning and the username and password fields never appeared. In other machines when I clicked on the WLAN name an error message appeared which said "Unabled to connect to this network". Instead of saying the authentication failed is better to say that I was unabled to connect to the network.
Regards,
Julián
