How to disable LAN connection at startup in Debian Jessie? Ido not know what establishes that connection. Is it any configuration file or my wicd that starts on boot. But when I open wicd I can see that connection via the wire is established after system startup. I do not want this connection because the modem connection does not work then. How to disable LAN on boot?
