Configuring an Access Point manually

  1. Connect Access Point to power and network similar to the procedure described in setting up the demo equipment
  2. Reset the AP by holding down the reset button for 10s
  3. Wait for it to reboot (flashing white light)
  4. Run PuTTY. You can download this from here
  5. Determine IP address of access point. Your DHCP server will probably tell you this. The access point's MAC address is displayed on its underside.
  6. Enter IP address in Host Name box and click Open:
  7. If you see a warning like the following, click Yes:
  8. Enter username as ubnt and password as ubnt
  9. Commands are:
    UniFi Command Line Interface - Ubiquiti Networks
       info                      display AP information
       set-default               restore to factory default
       set-inform <inform_url>   attempt inform URL (e.g. set-inform
       upgrade <firmware_url>    upgrade firmware (e.g. upgrade
       reboot                    reboot the AP
  10. Default inform_url is http://unifi:8080/inform (i.e. if you have a A or CNAME DNS record it will find the controller). To manually configure it, you will need to set explicitly with the following command. If you have a UniFi Gateway, you should use the name or IP address of that instead of The command is:
  11. Test connectivity to controller with info and ping. Info will show one of:
    • Status: Server Reject if the access point was able to contact the controller, but the controller has not yet adopted the access point - This is normal with a new access point
    • Status: Unable to resolve if you have entered the wrong address or DNS is not working (or CNAME is not configured).
    • Status: Unreachable if a firewall is blocking access to the controller
  12. If you have manually set the inform URL (e.g. to, the access point will send one request and, if the connection is successful, the controller will then know that the access point exists. However, the access point still needs to be adopted and assigned to your account. Therefore, please contact us to let us know the access is on and ready. We will link the access point to your account.
  13. Once the access point has been linked to your account, if you are using CNAME DNS it will autoconfigure. Otherwise, you will need to enter the set-inform command again
  14. Once the access point has successfully been adopted by the controller, you will be disconnected from your ssh PuTTY session and will not be able to connect in again as user ubnt. Therefore, if you enter the set-inform command and are not disconnected in a few seconds, you should assume the connection has failed and use the info command to see why.

Example transcript:

login as: ubnt
ubnt@'s password:<not shown>

1. please adopt it on the controller
2. issue the set-inform command again
3. <inform_url> will be saved after device is successfully managed
