I just purchased a macbook and I am going thorugh the initial start-up process and it is asking me to select a wi-fi provider and also to have a password for that provider. I have no idea which is the right provider to select and, therefore, I have no password. I was told at the store that, with my AirPort, I would be able to access the internet right out of the box. I am not planning on using wireless in my home, which is where I'm setting up the computer. I cannot access any menus or anything until I have completed start-up. Can anyone help me through this step? Thanks!
