Expert Q & A
How do I prevent neighbors from getting onto my wireless Internet network and surfing the Web on my dime?
Your wireless Internet access is made possible through a Wi-Fi router, such as an Apple AirPort. Your router allows you to set a password that is required to access your wireless Internet access.
To set the password on a Mac, go to your AirPort Admin Utility. On a PC, you can likely set your wireless router password through Microsoft Internet Explorer, as described in your router's instruction manual.
