Basically you don't need to do anything to access the internet unless you are behing a proxy server. A few basic questions
I suppose you are using ADSL. Is your LAN Card recognized by Ubuntu? There should be a Network Icon present in the top right corner of your screen in the system tray.
Is your PC a dhcp client? Is the gateway information correctly distributed by the dhcp server?

If you go to System -> Administration -> System Monitor
and click on the 'Resources' tab, can you see any activity under 'Network History'?
If you open a web browser (the default is firefox), what happens?
Is the 'wired' connection an ethernet connection or something else (eg. USB)?
Is it dialup or broadband?

When you try to go to a website (eg. google, what happens)?
When you click on the network indicator in the top right hand corner, what does it say underneath 'Wired Network'?
To get extra (advanced) information you can go to System -> Administration -> Network Tools.
To try to configure your connection, go to System -> Preferences -> Network Connections

Is this a new install? I did an install recently that didn't pick up my network card. However, the following solved it:
Add the following lines to: /etc/network/interfaces by doing:
sudo nano /etc/network/interfaces
and then add the following lines for DHCP
iface eth0 inet dhcp
or for a static IP
iface eth0 inet static
or whatever your IP to be
sudo /etc/init.d/networking restart

If you are using mobile broadband you can configure it via Network manager
Right click on the double arrow icon on top right of the panel-click edit connections then-mobile broadband -add ......
But to what device your ethernet cable is plugged?What does
ifconfig -asay ?
