- Make sure the controller-model and software version is compatible with this Prime version : https://www.cisco.com/c/dam/en/us/td/docs/net_mgmt/prime/infrastructure/3-0/supported/devices/pi30-supported-devices-list.xlsx
First step is to make sure the Prime error is actually TRUE. Check your 5760 controller and see if you find the AP.
If it's not there, then you need to make it join the controller.
If you find the AP on your controller, but Prime still throwing error - perform the WLC sync once again and then check the status.
If you have upgraded your Prime recently, make sure you have the recommended patch and device pack installed.
