I've recently discovered that the AI WLAN Auto Optimization feature isn't working anymore on my OC200 controller, since I've added an EAP655-Wall (v1) to it.

It keeps saying that my scan result is "Failed".

I've checked/enabled all of the features: Automatic Channel Optimization (all checked) and Automatic Power Optimization (all checked).

If I uncheck the Automatic Power Optimization for all bands, the AI WLAN Optimization works just fine.
