According to a thread in the forum
(http://ubuntuforums.org/showthread.php?t=1491242highlight=eth0+network+manager),
my disabled networking was probably caused after a hibernate locked up
the machine and I had to physically reboot it. Unfortunately, the
solution in the thread is for Ubuntu, not
I read a bit about the current network interface management system and
compared my setup with another Lucid install where networking works
fine. Ashutosh, you're correct: my /etc/network/interfaces should not
contain a line about eth0, Network Manager should pick up the hardware
and activate it
The network connection (for DHCP) should be either be allowed to
automatically get configured through the 'Network Connections GUI' OR by
including:
auto ethX
iface ethX inet dhcp
where X is replaced by your preferred network card's number. Not both.

1) Ensure that the /etc/network/interfaces file has no 'auto eth0..' only 'auto
lo'. Then create a new connections through 'Edit Connections' and enter the mac
address and keep ipv4 to 'Automatic (DHCP)'. At first it didn't work, but later
it did.
But before
Aha, thank you, I didn't realize that you had the same problem and that
going through the GUI was the recommended way.
Either way, whatever was done by default worked fine until some package
upgrade messed it up.
