can you check if the date & time on controller is correct or not ?
05-27-2021 01:51 AM
ON CONTROLLER TIME AND DATE ARE CORRECT BUT, IN AP TIME AND DATE WRONG

Look at the timestamps taken from the AP. The time and date changed three times.
Configure NTP first.
If the AP still does not join the controller, factory-reset the AP using the command "capwap ap erase all".
From the controller, post the complete output to the following command "sh ap join detail <AP MAC ADDRESS>".

"no join info"????
Can the AP ping 192.168.0.15 successfully?
05-31-2021 10:04 PM
Ap is pinging to controller and from controller to AP is also pinging

And if @Leo Laohoo suggestions don't help then see my post in https://community.cisco.com/t5/wireless/ap-showing-under-direct-aps/td-p/4196011
You'll need to capture the full logs from power on (well before capwap join starts) to catch the telltale logs of the hardware failure.
Just looked at your logs and don't see that there but you do have "DOT11_DRV[1]: wcp/RadDrv1 :: Dot11BaseDriver get_vap_if_index ioctl SIOCGIFINDEX failed for apr1v0 error No such device" so I wonder if it might be related.
I saw that on 8.5MR6 and yours is 8.5MR7 so they might have changed the logs you see when you hit that problem.
We are currently seeing around 10 of these failures each month on 1832 APs (orders of magnitude higher than other models) although Cisco insist that it's still within expected MTBF.
Either way TAC will be able to confirm if Leo's suggestions don't help.

how to check if the device has bugs or not. Any tool from cisco to know the status of AP if it has bug or not. how to know the AP is faulty any tool ???
