I'd carefully read and follow the terms and conditions posted in the cafe before considering connecting to their signal while off their property. Your local police department may not like this.
I live across the street from an internt cafe. I can pick
up the signal but it is very weak, i lose connection every few minutes. The distance from my apartmet to the cafe is about 400 feet. Is there a wireless card that would pick up the signal or am i too far away.
