Borked internets

[Jeffosaurus Rex]

I switched the OS on my other computer from Ubuntu to Windows 7. Ubuntu automatically connects to the internet. Windows 7 does not find any connections.

The computer is connected to a gateway with an ethernet cable, like this one.

1: Hao do I internet?
2: Why would windows make it such a hassle while Ubuntu does all of the work for you and it's free?

Edit: ATT says you don't have to download any drivers.
