@KingOfGitH
when configuring network settings such as NetworkManager on Linux, wsl may not be able to communicate, but i do not see anything wrong with the information provided.
send logs to https://github.com/microsoft/WSL/issues and microsoft may be able to provide a solution.

you can try it.

$ sudo systemctl --now enable network-mirrored

Very grateful for this, spent countless hours trying to figure it out, no amount of gpt could save me.
