You need to manually define it as described in README.md in /boot/firmware
- Bypass the Wi-Fi configuration through Repetier-Server.
If a file "/boot/firmware/ManualWifi.conf"
exists, we will copy this file for Wi-Fi configuration and prevent modification
of Wi-Fi settings by Repetier-Server. The /boot/firmware folder is also accessible if you mount the sd card
on a Windows computer, so it can be defined without direct access. Make sure to use unix line encoding!
There is a sample config file "/boot/firmware/ManualWifi.conf.sample" for convenience.
Then you bypass our solution and can do anything you want or need.
