How do you setup the internet on Ubtunto?

My friend installed Ubunto on an extra hard drive. The internet (cable) was working fine on Windows, but After installing Ubuntu, we can't get a connection. Shouldn't the internet automatically work? Help some linux noobs get the internet working!

Update: We typed the command "sudo pppoeconf" in the terminal to configure the broadband connection, but it says:

"Sorry, I scanned 2 interfaces, but the Access Concentrator of your provider did not respond. Please check your network and modem cables. Another reason for the scan failure may also be another running pppoe process which controls the modem."

*Fixed*

He reinstalled Ubuntu and his internet started working.

It asks for a password. When the administrator password is entered, it says:

I do believe that means your machine doesn't know its address. (At least it would mean that in Windows.) This could get a little ugly.

Normally, I would expect your cable modem to have a "DHCP server" available to be turned on. If you can do that, your Linux machine should see the internet fine - but you probably need an IP address to access the cable modem! If you can still boot to Windows, you can change it from there. Otherwise, here's a howto on static IP addressing in Linux
