How can I block users w/ notebook and laptops from using my home internet connection? I am not good w/ computers at all so I have no clue! My nephew who has laptop and is not allowed on internet (unless at home w/ parents under supervision) is able to connect when he comes over. Im assuming he is using my network or something? Like I said, I'm really that bad when it comes to computers! I have a home computer w/ internet through my cable provider. Is he able to log on because of that?
What can I do to stop users? Also, I have a neighbor who will come and sit on my patio to use my connection w/ his laptop! He isn't the one paying the bill so I want it to stop!
What can I do? (oh and please, speak in terms I can understand when responding! )
