@LincolnDJ You have any POE devices connected to the 655-WALL? I had something similiar when I had POE enabled and had a POE power adapter connected.

  @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 adapter - but I'd rather not long-term lol 

Hi  @LincolnDJ 

Your SDN devices (gateway routers, switches, or EAP) may have lost contact with the controller if your controller log is filled with messages stating that they are often disconnecting and reconnecting. The following procedures can be used to verify that the controller and SDN devices are connected, even while the internet is unaffected:
    1) Examine the quality of the wire that is plugged into the controller;
    2) Examine the controller's hardware;
    3) Replace the controller's power source to ensure a steady power spply;
    4) Update the firmware version to the latest.

  @Vincent-TP  Hi, thanks for the reply and apologies for the delayed response (I've been working away for 7 weeks).

I have swapped the wall device for one of the EAP650 (and vice versa) and the fault stayed with the EAP655-wall - so this rules out cable issue, and issue with the specific port on the ER7212PC. And in answer to your replies:

  1) wiring is good. Works fine with the EAP650's

  2) what would you recommend examining exactly please? the ER7212PC is brand new and in physically good condition. Latest firmware installed.

  3) it shipped with only 1 power supply. It is powering only 2x EAP650 and the 1x EAP655-wall so should be well capable of powering them all. I can try with one of the EAP650s disconnected to see if there's any change. For the Router, CPU usage is 3% and 83% of the 90.9W PoE is still available.

  4) All hardware is latest firmware.

Is it possible the EAP655-wall has an issue and needs to be replaced?

Hi  @LincolnDJ 

Is the EAP650-wall's Internet affected?

If yes, you may contact the retailer to check the warranty.

If the Internet is not affected, you may disable the notification on the APP.
