Failure to adopt TL-R605 after firmware upgrade
this is the second time this happens. I have a setup consisting of a few switches, a few EAPs and a TL-R605 router. When I upgrade the firmware on my core switch or the router itself, Omada controller (software based) complains about the router failing to adopt; specifically, it shows the router as "Adopt Failed" and it cannot be managed. If I press the "retry" button, it's asking about the username/password of the device, as if it was managed by some other instance of Omada SDN.
Has anyone faced this issue before? Is there some fix?
