I've tried to readopt the gateway, and it fails after a long time "adopting". The web interface doesn't say that it is being controlled by Omada, but If I attempt to log in with the username and password I had set up before it was adopted for the first time I get "incorrect username or password".

I'd like to add additional information here.

Since the gateway was managed by the controller before, the username and password of the gateway should be the same as that preset under Settings -> Site -> Device Account on the controller, you may confirm you have the right information there.

That was the piece of information I needed. Sadly for me, I had already reset the gateway.

On the bright, I will never forget about this setting again.

Sorry for my late information. Hope everything works good now.

Sorry if i response first. but that settings is similar to what on my controller. when i view the password it is also the same password on my controller.

No worries, next time you may know that the password under Device Account could be different from the login password of the Controller itself, it depends on what you configured that settings before.

For the Device Account, the username is admin and the password is generated randomly by default. And since the upgrade of Omada Controller v5.1, the Device Account configuration has been added to both Quick Setup and Add New Site to emphasize it presence.
