Troubleshooting Issues with UniFi AP Adoption

Are you experiencing trouble adding a new UniFi Access Point (AP) to your existing setup? Have you tried using the latest firmware and following the manual instructions, but still unable to get it added to your device list? You're not alone. In this article, we'll explore some common issues and provide step-by-step solutions to help you successfully adopt a new UniFi AP.

Background Information

I have an AC-Pro connected to my controller, which has been running for almost a year now. The device is upgraded to the latest firmware (version 3), and the controller is on the latest Docker build. I've followed all the manual instructions, including using the iOS app, Chrome extension, and SSH, but nothing seems to work.

The Problem

The new AP will not show up in my device list and remains stuck in the client list. After a few seconds, I receive a message that the device is adopted, but 2 seconds later it's discovered again. I can send the inform command and click the Adopt button in the controller, but the AP doesn't get added to my devices.

What to Expect

When you press the 'Adopt' button over SSH, you expect the AP to be added to your device list. However, this is not happening for me, even though I've followed all the instructions.

Docker Configuration

I'm using the latest Docker command and docker-compose.yml file to launch the container (omitting sensitive values). The unit will then reboot, and I can reconnect via SSH to check its status by issuing a 'info' command, which displays its status and whether it has connected to my controller.

Setting Up the Controller

I've used the settings as told in DockerHub. If you're using a GUI, please provide a screenshot of your configuration page. For those who are new to UniFi, here's what you need to do:

1. Change the IP or FQDN of the controller to the values appropriate for your network.

2. Once the AP reboots, you can then SSH back in and log in using the default username and password.

3. Perform a factory reset by typing 'set-default to factory reset'.

4. If the AP was previously managed, get the username and password from the old controller under System Settings > Controller Configuration > Device SSH Authentication.

Adding a new UniFi AP can be challenging if you're not familiar with the process. However, by following these step-by-step instructions, you should be able to successfully adopt your new AP. Remember to check for firmware updates and ensure that your controller is on the latest build before attempting adoption. If you're still experiencing issues, please provide more details about your setup and configuration.
