Public bug reported:
PROBLEM:
Fresh install of Ubuntu 9.10 on a Lenovo (IBM) ThinkCentre M58e did not
recognize or connect to a wired network connection via DHCP. Changes to
/etc/network/interfaces and /etc/NetworkManager/nm-system-settings.conf did not
help solve in any combination.
INFORMATION:
ifconfig returns:

/etc/network/interfaces :

#iface eth0 inet dhcp

/etc/NetworkManager/nm-system-settings.conf :
"
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in
# the file:
#
# /etc/default/NetworkManager
#
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=true
"
SOLUTION:
Adding the line to "e1000" (without quotes) to the file /etc/modules allows for
the recognition of the wired network and results in near immediate connection
to the internet.
/etc/modules :
"
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
lp
e1000
