We have an RFS4000 Controller and we relocated one of the associated AP7522 AP’s. We were having a few connection problems so I rebooted the controller. Now, all 30 AP’s are showing as offline and they look as thought they have stopped communicating with he controller. I have rebooted the controller a few times but I don’t see any of the devices. I’m not sure where I go from here.

It sounds like the APs have lost their ability to adopt to the controller.

If the APs are layer-3 adopted, verify that a connection between the APs and controller still still exist. (Can you PING the APs from the controller?). This adoption connection also requires UDP port 24576, so make sure this isn’t being blocked now.

Or, are the APs on the same VLAN as the controller? (layer-2 adoption)
