Upside Down

Question. You find out that your neighbour is stealing your wireless internet. What do you do?

First of all, what the heck are you doing with an unsecured wireless network? Learn to secure your wireless network. Read your user manual or go ask someone who knows.

Assuming that you do know how secure a network but you are just sharing your bandwidth wealth, then you might know how to mess around with your neighbour's internet connection by turning it upside (see link below):

Actually I have no idea if it really works or not. Interesting though...

Nonetheless, I think it is probably illegal for your neighbour to be hopping onto your network because you are breaching your contract. There is probably something in your service agreement with your Internet Service Provider that says you should not be sharing your internet connection with others. Your neighbour should be paying for his/her internet anyways; as if your internet connection cannot be fast enough.
