Security is a major concern with any device that connects to the Internet. Your wireless router comes with some security features built in, but you have to know how to use them. Your router has either WEP or WPA encryption. If you have the option, WPA is far superior. With regularly changing keys, WPA makes it incredibly difficult to hack into your Wi-Fi network.

Though your router undoubtedly has encryption features, they’re typically turned off for shipping. Make sure you actively enable encryption. Don’t just assume it’s working. Run a firewall on computers connected to your Wi-Fi for added security.
