Probably not being able to help you, but your post is lacking some information for anybody to be able to help.

Which version of Ubuntu (12.04, 11.10, ...)?
What 'device' do you normally use? Wifi to connect to router; cable to connect to router? 3G USB modem (which one)? Analog modem? Other?
For those local to your area, which provider?

What exactly is not working? Is the machine connected to the Internet via some other method? Does your Ethernet connect into a local LAN or into something like a DSL modem?

You need to provide details on your setup before anyoen can help.

Hi,

if it is dhcp, and assuming the device is eth0, you need to have a line like the following in your /etc/network/interfaces file

Code:

iface eth0 inet dhcp

Then run the command

Code:

sudo ifup eth0

If you want it to automatically come up at boot time you can add the "auto" declaration for eth0 in you interfaces file.
Ie.

Code:

auto eth0
iface eth0 inet dhcp
