are you using DHCP to get an IP Address?
if so - try running:

sudo dhclient eth0

on the commandline to see if it works then.

if not try running the following command on the commandline:

sudo ifconfig eth0 192.168.0.20
sudo route add default gw 192.168.0.1

to make your DNS work you will have to put the following line
into /etc/resolv.conf as the first line.

nameserver 192.168.0.30

You can edit this file by issuing the command:

sudo kedit /etc/resolv.conf

on the commandline

you have to substitute 192.168.0.20 with your IP Address, 192.168.0.1
with your gateway and 192.168.0.30 with your DNS Server.

depending on wheter you use DHCP or a static IP Address you have to
modify /etc/network/interfaces.

man interfaces

on the commandline should help you with setting this up.
