Run netconfig as root, auto probe for your nic, then set up the the net for whatever you are using, whether dsl, cable etc. If you use dsl with dhcp, just enter any name for the name, localdomain for the domain, select dhcp, and leave the rest blank, in other words don't try to set a dhcp address or domain address.
