1130AG AP RADIUS Suport

[aricardor]

I have RADIUS from Windows 2016. It works fine until 4 days. I see error 22 in Event, security, problem with EAP. Finally, I configured the 20 AP with WPA2 without RADIUS, pre-shared key.
The AP are AIR-AP1131AG-E-K9, firmware version 12.3(8)JA2, 10 o more years old.
Is it compatible RADIUS from Windows 2016 with that model o firmware?
Thanks!

Yes, the AP is just a middle man if using external RADIUS so it shouldn't matter which server is used. Seeing as it was working, there must be another issue on either client or server side.. what policy/eap type are you using on the server?

Check the NPS certificate.

The AP will work with that RADIUS server.

As it stopped working 4 days ago, check the certificate on the RADIUS server.

Ensure that the AP or WLC (dependent on if LWAP or autonomous mode) is added as a network device to RADIUS. 

You should be able to look at the RADIUS logs to understand why its failing and search the error codes given in the NPS forums
