WIFI Controller C5210 - "Unable to connect to RADIUS servers"

Greetings,

We are using an extremE controller C5210 with WS-AP3715I Access Points and are getting a "Unable to connect to RADIUS servers" when ever we want to connect.

We have rebooted the radius server and the controller to NO avail.

Any pointers?

Thanks,
Kombe

Hello Kombe,

Sorry you are still having issues. I would suggest contacting the GTAC for assistance. Someone can review all of your configurations and assist.

Just some background on this issue. We are using an extreme controller C5210 with WS-AP3715I Access Points and are getting a "Unable to connect to RADIUS servers" whenever we want to connect.

The certificates expired on the Windows server DC and now NPS Network policy, can not get certificate. On the DC when we hit edit, we get:

Cannot configure EAP
A certificate could not be found that can be used with this Extensible Authentication Protocol

We have rebooted the radius server and the controller to NO avail.

Any pointers?

Thanks,
Kombe
