Wow, it's so containerized and isolated that it can't even see the Wi-Fi, or it just hasn't the permission to connect, but I suppose that you enabled it when you installed it if you could at least reach a settings section. Otherwise I have no idea about why it doesn't work.

Do you have UFW Firewall enabled?
Do you have dbus-x11 installed?
