As far as I'm aware, there are no clear cut laws on wi-fi/wireless internet leeching. It ends up being a question of morality and safety/security. If you do end up using your neighbour's network, I would strongly advise against doing any personal online banking or any other "secure" transactions. Don't waste their bandwidth either for downloading shitloads of stuff. That then becomes a liability which push comes to shove you may end up having to pay for. Exactly who is leeching your bandwidth is quite easy to track down for the ISP.
