Thanks for the Advice. Im not worried too much about my data as most of it is game data packages. I have a pretty good idea who it is. I saw somthing strange from the window of a house 5 doors down the other night, as i was drivng to my house from the top window I could see a blue blinking light small but bright then today the same window has a round silver thing looks like a culander with what looks like a wifi stick. poss directional wifi (home made) I have a 22 air rifel so im going to shoot it next time I see someone connected.

I have found that someone local is using my intenet connection on my "secure router" anyway im not that arsed that they have bypassed it I have been meaning to only allow mac address but just to lazy lol. Now that I have somoene on my network instead of just shitting them off I want to have a little fun with them first...

I want to know what I can do with them? I have heard about being able to fool his computer into thinking my PC is the router and being able to see what he is using my net for? also would like to teach him a lesson without distroying his stuff. I think I could have some fun if someone can tell me what to do.
