route -n

If I run sudo dhclient3 eth0 I do not get an ip.

Any clues? This is on an older Gateway laptop.

If you can ping the loopback, Good, you're interface card is working.

- Are you sure you're connecting to a DHCP-serving device?
- Check the patch-cable if it is not damaged/Try using other patch cable.

HTH.
