I have a video surveillance system, often the cameras disconnect from the NVR connected to the same wired network. It seems as if ap isolation was set but I can't find any similar entry in the oc200 system.

it often happens that the 2 eap225 disconnect from the controller and I can't recover them until they return by themselves...
this is very annoying because I can't find the solution... if there are language errors it's because I'm using google translator.

I don't know if it can help you but I'll describe how the system is composed. 
router provaider to follow oc200, the lan output powers a switch that is not poe, from the switch come out 3 risers that for n.2 eap225 and n.1 eap610 that in mash manages n.2 eap610.

grazie a chi mi aiuterà
