1. Go to your neighbors house tell him he has an unsecured wireless network and you will charge $50 to train him how to set it up properly.
2. Hack into his wireless box and block your wireless card or disable his SSID broadcast.
3. Access his wireless network and download a bunch of illegal software. The Police will show up at his door and take all his computer equipment including his wireless router. You have to do this just right or they may catch you. Since you do not know how to do this right DO NOT do this.
Another thought did you set up your wireless manually or did you use the auto connect. I use the manual connection and don't have problems.
