Great thread! Thanks for all the input. I did not read the notes and upgraded my OC200. Like everyone here, did not realize until too late that V1 hardware is not supported. Luckily I had backups for my SSID's, followed your suggestions, downgraded the controller, reset the AP's and adopted them. I am back up and running now. Considering the AX1800 or AX3600 access points, but this allows me to think about it and upgrade on my own pace. Thanks all for the thorough thread!
