After 60 seconds of trying to join a controller with CAPWAP, the access point falls back to using LWAPP.
If it cannot find a controller using LWAPP within 60 seconds, it tries again to join a controller using CAPWAP.
The access point repeats this cycle of switching from CAPWAP to LWAPP and back again every 60 seconds until it joins a controller.
Once the access point downloads the CAPWAP image from the controller, it uses only CAPWAP to communicate with the controller.
