And if it is down on the WLC then why?
- Does the AP have enough power?
- Is it configured correctly?
- Is the country configured correctly?
- Is the AP the correct regulatory domain for the country?

Have you checked the controller config with https://cway.cisco.com/wireless-config-analyzer/ using the output of "show tech wireless"?
