Do you have a green icon with black bars on it (at bottom rigth hand corner of screen? If so click that and choose your router or service providor. If you have done that then you need to get the Username and Password which your providor should have given to you. And access it by typing something in your Internet Broswer. In my case as i am on BT i had to type 192.168.1.1 (the default) and set it up via there.
