Please let us know the AP models, Controller currently running version, AP Zone version. Are there any other APs that are online with config status up-to-date and radios enabled?
Please login into the AP CLI and execute the command "get wlanlist", "get power-mode". Did we try to create a new Zone, not clone and move the AP to the new zone and verify if the same issue is being reported?
The above info will help us to narrow down the issue.
