- SSH to ubnt:192.168.1.20 (or whatever the IP address is.)
default password is ubnt, if it something else, I hope you wrote it down when you set it. :) You must reset the AP to defaults before changing the inform ip address. To do so execute the following command
syswrapper.sh restore-default
This will reboot the radio and disconnect your SSH session. Once it comes back online, you will need to reconnect.
Connect to the mca client
mca-cli
Now issue the set-inform command with the IP address of your Unifi controller.
set-inform http://192.168.3.2:8080/inform
The AP should connect to the controller within a few seconds and you are set.
Adopting a UniFi device
Use a default site, as some credentials are being changed to a site, then you won't be able to adopt the device (see link)
