When your device is getting old…

That’s a new one. The certificate on my old old WLC is expired.
So last night, after a power outage, none of my access points were able to rejoin the controller.

So after some debug, the following error showed up on the access point.

Google is your friend, and I found a Cisco Field Notice: FN – 63942
And after turning of NTP, change the date/clock back in time, the AP start joining again, and to keep it a bit more permanent the following config was added to the WLC config.

 

Maybe it’s time change out my wireless setup, but not yet, It is still working as a charm. 🙂
