1. Disable NM with
update-rc.d network-manager disable
You can enable it later by replacing "disable" with "enable". Note,
you will temporarily lose any capability for wireless connectivity,
2. In /etc/network/interfaces have only the loopback interface (lo) plus
allow-hotplug eth0
iface eth0 inet dhcp
3. Now do
ifdown -v eth0
followed by (noting any screen output)
ifup -v eth0
Or reboot. Or both.
This should give you a reasonable idea whether the machine communicates
with the router.
