WLC-2504 APs' are now rogue

[joseph.ashley]

Hey folks, I've work for a small college. I have seven Cisco Aironet 1142 APs' in my network. They have been working fine forever, but this morning I came to work and wireless is down. In the controller, all the APs are showing as rogue, and I'm at a loss on how to get this resolved.

not sure we have not seen this issue before :

1. can you post show the version code running on WLC

2. can you turn off one of AP and see if that works as expected ?

Software version: 8.0.120.0

I have rebooted the controller and the APs. It didn't resolve the issue

8.0.120.0 is one of the affected version to the FN that @marce1000 posted.

Hello,

check if rogue detection has been enabled on the WLC (default is disabled)...

Georg,

Attached is a screenshot. Not sure how to interpret it though

I upgraded the controller software to 8.3.143.0, disabled NTP, changed the controller date/time to a day prior to the cert expiration and was able to adopt the aps' which then got the updated software pushed to them from the controller. Everything is working now. Thanks for the help!!

If you're using 8.3 you should upgrade to the last 8.3 release 8.3.150.0

Of course this whole lot is very old so you need to start thinking about replacement ...
