Verify that you have something similar to the following in /etc/network/interfaces

auto eth0
iface eth0 inet dhcp

eth0 could also be referred to as p5p1 or similar according to the modern naming convention.

You can 'restart' all the network interfaces by bringing them down and up again with the following command: ifdown --all --no-loopback && ifup --all --no-loopback or a specific interface, eg: ifup eth0

If your conf seems in order, then try modprobe tg3 and then bring up the network interface using ifup. Might be an issue regarding the drivers or lack thereof.
