Had the same problem. I upgraded from feisty and the network-manager behaviour changed.
Make shure that all interfaces in /etc/network/interfaces are commented out (except for lo). auto lo iface lo inet loopback #auto eth0 #iface eth0 inet dhcp #auto eth1 #iface eth1 inet dhcp Is this you problem, too?
