I have one an issue that I would be extremely grateful for help with. When I check the AP join statistics I see the following:
Reason For Last Unsuccessful Attempt RADIUS authorization is pending for the AP
I don't run a radius server and don't know how to get around this so that the device can join.
Thanks in advance for your help!!
What model and version is your WLC? We ran into something similar a couple years ago when we put our first 1142 LAP in. I don't remember if we encountered this specific error, but what we did learn was that the WLC 2100 series requires software version 5.2 or later to talk to the 1140 series LAPs.
If that isn't it, Cisco has a pretty lengthy troubleshooting document that might be of help.
