Wireless

Hey guys, I'm leeching off of my neighbors internet right now, and I saw their shared music in iTunes. Since I can see their stuff, does that mean that they can see that I'm connected to their internet? How do I remain invisible? thanks

Meh, getting past WEP is very, very easy these days (can be broken in less than 15 minutes, google says truth) you'd be better off getting the router to only 'talk' to MAC addresses that user defines.
