I have a functioning Omada network with an ER605v2 gateway, SG2008v3 switch, an AC200 controller, and a bunch of EAP225 APs (indoor v3 and outdoor v1 + v3).  The firmware is up-to-date on all of them and the system is working fine.

I picked up an EAP245v1.1 and updated the firmware to current.  It wasn't recognized over the air.  I hardwired it into the network and got an error message, "This device is not compatible with the current controller."

Since the firmware is current on all devices, and my other APs work well, I don't know why this EAP245 isn't being accepted.  Any help would be appreciated...
