ROFL! We have a teenaged neighbor who I think occasionally leached on our wi-fi. I never realized that I could have had fun with him like that! Funny thing is, I got him in trouble by asking his mom about his connection. She doesn't know anything about computers, so when she mentioned on the phone one day that he had to be sitting at the window (the one closest to our house) to use the "fast internet" instead of their dial-up, I casually asked her what network he was on. Linksys. Uhm, yeah, very likely that's us. So the next time we were down, I called and asked her if he was having trouble getting his fast connection. She said yes and asked how I knew, and I said, "Oh, because we are down and I am pretty sure he has been using our connection." She was not happy and told him he had better NEVER steal someone else's service again. I didn't even have to complain about it, just make her aware of it.
