Well, I have been trying to download some software for my mac but all of a sudden my internet is too slow to download it. I downloaded a application that hows whats connected to my wifi. It turns out that my next door neighbor's son has his iPod, xbox, laptop, and iphone connected to my internet. I have a MAC so please tell me how to kick him off or ban him. Any thing works i just want him off!
