You can not use network manager cause you setup network with ppoeconf or manually trough editing of /etc/network/interfaces. Just comment eth0 and pppoe entries int /etc/network/interfaces so it looks like this:
auto lo
iface lo inet loopback

#auto dsl-provider
#iface dsl-provider inet ppp
#pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
#provider dsl-provider

#auto eth0
#iface eth0 inet manual
