adoption failed: unifi AP

Hello,

 

my unifi network worked great few hours ago, I needed to change some vlan settings , which didn't work, afterwords I've changed all the settings to the original ones but one of the twoo acces points fails over and over adopting to the controller.

 

I allready tried adopting with the standerd username/ pasword: ubnt/ubnt but this did not work,

Allready tried the reset button on the ap itself , powercycled several times but nothing worked so far. For so far as I know all my clients are connected with it and receiving internet from it, but it stays unmanagable from the controller.

 

I also tried sshing into it from the cmd, but the connection is refused. I also issued a ping command to it which it succesfully did without issues 

 

kind regards,

Wouter Vermeersch

Hello @woutery,

 

Forget the UAP in the controller and hold the reset button for 10 seconds.

Re: adoption failed: unifi AP

I would buy you a beer if you were near! I have spent a while trying in vain to accomplish adoption of my AC-M and came back to have another look on these forums and found your solution. It is forgetting the UAP that completes the fix! I tried a pin reset for 10 seconds without success, I forgot the UAP and bingo!
