Do you offer free internet for your neighbors? If you run a wireless network you could be giving out free internet access to your neighbors running the risk of allowing others to gain access to your personal information or files on your computer. Some users of Wi-Fi networks do not realize the importance of manipulating the security settings on a Wi-Fi router to keep outsiders from accessing your network. You may be responsible for any illegal activity that takes place on your internet access whether you committed the crime yourself or your neighbor that has access to your network did the crime. It is best to protect yourself and your personal information by securing your wireless network. (via)
