@tukane So you have migrated it and it works, but devices are all disconnected on the controller, right? reboot? Are devices working still? Can you ping them from the controller?

@janaca Is the router stable when OC is offline? Did you have a reboot schedule configured? How did you power it? Tried with different cables to rule out the power supply unstable problem.

@rakrouki Try logging with HTTPs, different web browsers and private windows.If you see the Advance or Accept the Risk, click keep going.

@DrPollocks Good to hear you found the root of your issue, no forget to update here.

@leonas Need the omada gateway or omada switch on the controller, only the EAPs cannot report the accurate info to the controller.

@mackworth Omada doesn't support copy SSID settings, you can find the similar request thread if you search in the forum.
