Basically, my comp is the MAIN internet comp. I.e modem thing is plugged into my comp. got my bros laptop, mums laptop, dads laptop ,and dads desktop, All able to connect to this connection. Thats cool. But so can anyone else?? How do i secure it so no-one else can use it? Ive tried before, but had trouble and i cant remember how i even did what i did before? Any advice would be much appreciated. Cheers
