Hi ,
The AP and Rap were used for a few years, and they all should be licensed.
I provisioned the AP by connecting the ap to the controller directly , and go to configuration/ap installation/provision, then select the ap , set the controller ip address, ap group name ,ap name, then click Apply./reboot . Once the Ap reboot up , I disconnec the ap from the controller. In the beginning , AP/RAP work fine, but after some days, the AP ./RaP lose the configuration , like AP name....
