I named mine "No more wireless leechers" when my dumbass neighbor happened to mention that he doesn't have internet at his house, he just uses somebody else's in the neighborhood that was labeled "Homenet" which is what I used to call it. I locked her down and relabeled it. I know, it was stupid of me to have it unsecured, but at least I got to have some fun at his expense. And yes, I still broadcast the SSID. He's not tech savvy at all, so I'm not worried about him trying to hack it. I have a very secure password.
My router is in my basement and I barely got a passable signal on my second floor and none on my front porch so I figured there was no way it was getting to my neighbor's house. Umm, wrong!
