I have done many searches and my questions have not been answered to my satisfaction. I'm sure it is because I don't understand it all yet. Question 1, My neighbor is a real d*&k and has wireless set up, according to him he can pick up any computer a long ways away. My new iMac (2 wks old) can he hack it even if I don't have any wireless set up on it yet? Question 2, I have Airport Express to use only for my speakers and possibly a wireless printer down the road. The Airport Express will be used in one room only and it is the room directly across from the the room he has his station set up in (approximately 16'). If I hook the Express up, how do I stop him from hacking my system via his wireless base station to access my iMac? I know I am a little paranoid, but I just don't trust this guy at all. I know search is my friend and I have tried to us it, but I guess I'm not smart enough about wireless to feel comfortable. So thank you in advance for your knowledge on the subject.
