Can you please confirm the last flag you are seeing, is this either "l" or "I".
L = Unlicensed : Check you have enough licenses available for the RAP. (#show license limits)
I = Inactive : As what @dojjan said, check you have the necessary VLAN's in place on the controller which is terminating the RAP. On the controller where the RAP terminates, run the command #show profile-errors to see if there is any errors with your configuration.
