Need help to configure network

[Joulinar]

We did something like this in past using a tool called ifplugd

Using ethernet + WLAN interfaces (not at the same time) in v6.30

I wanted to use my raspberry 4 connected with ethernet and sometimes bring it to the tv where there is no ethernet cable and i have to use WLAN. In order to do it reliably and automatically, emulating what you get in desktop computers like a laptop, which disconnects to wifi when connected to ethernet and connects to wifi when there is no ethernet connected, i used ifplugd. Also, using this method you can have both interfaces with the same static ip, which may or may not work but it is up to you…
