Hello Leo, the upgrade is not possible, the upgrade has been made a few months ago.

Please keep in mind:

The current issue should be this.

I don't understand why this message is there:

tanner.zaitt · ‎06-17-2021

Yes, the AP is powered by POE port from Poe switch.

The output of the dir command is:

Event log file has not changed. So this means it is not a crash but a power failure.

Does switch have any log indications when the AP goes down?

tanner.zaitt · ‎06-18-2021

I see only these logs in the switch and in the sys log server:

Move the AP to a different switch member, different port and observe if the ports is still unstable.

Scott Fella · ‎06-17-2021

That is the last known reason.... what does the show ap uptime show? Is this ap not joining and continuing to bounce? Don't focus on that message as at times, its very generic.

Uptime is short from the incident to now.

The AP has been joined to the WLC controller and works as expected.

Scott Fella · ‎06-18-2021

Sometimes the ap will crash but you should have some sort of crash dump in the flash and at times you don’t. You don’t have any other controllers in the network that are on a different code by chance.
