I'm kind of new to the whole techie thing, so bear with me. We have the airport connect for my laptop and my boyfriend's desktop computers so that we can hook up to the internet. Seems that our neighbors are hoping on the internet right on with us using our account. How do we make it so that only my boyfriend, me and any lucky houseguest who get our passwords, can get on the web through our account. Simple Basic but I'm too ignorant to know the answers. Muchas gracias.
