Ubuntu 7.04 Feisty Fawn how-to: stuck on page 3

[Nocturnal]

I'm stuck on page 4.

I was able to successfully install ssh.

I then type:

vi /etc/network/interfaces

I'm then greeted with the next step which is to I guess type in the IP, gateway, etc.

The only thing is, I see this:

~
~
~
~

When I attempt to go there via hitting enter on the keyboard nothing happens.

Am I already supposed to see the network settings there?

If so, what might be going wrong? Perhaps the driver for my NIC is not install or needs to be installed?
