@GoodOmens hi thanks for the reply. The AP is powered via PoE from a ER7212PC router/switch, and there's nothing connected to any of the 3 ports on the AP itself. I could try powering it from the AC...

I keep getting repeated "xxx was connected" events on my EAP655-Wall. Firmward has been updated. No actual connection issues in use as far as I can make out. And not getting any disconnected alerts...
