The /etc/network/interfaces file is the configuration file for ifupdown. If you want NetworkManager to manage an interface then remove that interface from /etc/network/interfaces. A minimum file would contain only the loopback device. auto lo iface lo inet loopback That is it. Nothing else. That will set up the loopback device but not configure any other device. Since other devices are not listed they will be configured by either NetworkManager or wicd whichever is installed. > Which entries are containing in interfaces as default?
