text: how can i tell if someone is piggybacking on my wireless connection ?   wow...i didn't even know people could do that! is nothing sacred?  oh...internet wireless. i thought you meant cell phone. lol   actually, i used my niehbors for about 4 months. i couldn't help it, my comp just recognized their signal. you have to put a password on it. if you don't it's just open to everyone.
