If you are only using a modem, insert a ethernet cable into the modem and your netbook. You should get access to the internet right away.
If you are trying to connect wirelessly through a router, it really depends on what type of router that you have and the type of security that you have enabled. In most cases, all you should have to do is enter in a passcode or passkey to gain access.
You might also want to make sure that your wireless card is turned on. You can usually find a little switch with an picture of an antenna with half circles coming off of it.
