When I restart my network as per the Perfect Setup tutorial, I get the following errors: Code: root@ww2:~# /etc/init.d/networking restart * Reconfiguring network interfaces... eth1: ERROR while getting interface flags: No such device There is already a pid file /var/run/dhclient.eth1.pid with pid 134993416 Internet Systems Consortium DHCP Client V3.0.4 Copyright 2004-2006 Internet Systems Consortium.

After looking at other posts in the forum, it looks like I'm missing the module for my NIC, but how do I figure out which module I need? I am running Ubuntu Feisty Fawn on a Dell Dimension 4100. I can still access the internet, and everything else seems to work fine. Thanks.
