Hello @Amoanster,

Thanks for reporting this issue to TP-Link community!

First, you probably know that a "device was disconnected" log means that the device has lost connection with the Omada controller for more than 5 minutes. When the device is changed back to "Connected" state very quickly, the controller cannot sense its status change but will only report with "device was connected", that's why you only get one "AP was connected" log.

Generally speaking, we may get a single "device was connected" log when the device was rebooted. You can click the reboot icon on an AP from the Devices list of your Controller to have a test.

Please confirm whether EAPs are actually working properly, and check the total power consumption and the physical connection.
