@MarioRuck No, the closest you get to high availability is to have a spare in the shelf, (cold spare)

@himemsys There is no problem using the OC200 to manage the EAP610, you don't need a switch or router

@DACZ try disabling IPS/IDS, the router is too weak for that.

@Fae I upgraded without major problems, a remote site with ER707-M2 with fixed ip lost the connection, the internet settings changed from fixed ip to dynamic ip since there is no dhcp server for WAN...

@BobbyBrittle can you show a screenshot of your SSID configuration?

@Magnus33 Could there be a loop in the network? try and disable mesh on the controller to see if that helps. are there several cables connected to the access point that can create a loop?
