Since the new update to UniFi OS 3.x, Ubiquti has removed support for podman, which some may have been relying on for wpa_supplicant to bypass the AT&T Fiber Residential Gateway. There are ways to launch an equivalent container with nspawn-container, but I haven't been able to get it to work with nspawn. In any case, here's a file to run it directly on UniFi OS and make it persistent!

Trying to keep it simple as possible. Enjoy!

1. Get certs (I assume you have this already if you’re looking to make this work for UniFi OS 3.x)
2. Download this package/folder (wpa_supplicant).
3. Copy certs to wpa_supplicant folder package
   • Rename as:
     • CA.pem
     • Client.pem
     • PrivateKey.pem
4. Update the MAC Address of your certs in wpa_supplicant.config.
5. Enable SSH on UDM/UDM Pro/UDM SE
6. SSH to UDM/UDM Pro/UDM SE as root user.
7. SCP wpa_supplicant folder to /data
8. cd /data/wpa_supplicant
9. chmod +x install.sh
10. ./install.sh
