Press Alt+F2 and in that window type in 'gksudo gedit /etc/network/interfaces' (or 'kdesu kate /etc/network/interfaces' if you're using KDE) and comment out all the lines relating to the network. You'll probably see something similar to this:

auto eth0
iface eth0 inet static
   address 192.168.0.100
   subnet 255.255.255.0
   broadcast 192.168.0.255
   gateway 192.168.0.1

Comment out all those lines (put a # at the start) and it should look more like this:

#auto eth0
#iface eth0 inet static
# address 192.168.0.100
# subnet 255.255.255.0
# broadcast 192.168.0.255
# gateway 192.168.0.1

NetworkManager won't manage any interface uncommented in that file. Don't comment out the lines with 'lo' in them, those are important to have there :)
