Wi-Fi Protected Access (WPA or WPA2), which can help protect your wireless network. It’s important to help secure your wireless network by setting up a network security key, which turns on encryption. With encryption, people can't connect to your network without the security key, and all information sent across your network is encrypted so that only computers with the key to decrypt the information can read it. This can help prevent attempts to access your network and files without your permission.

Wireless encryption (WEP) is not as secure. Windows 7, Windows Vista Service Pack 2, and Windows XP Service Pack 3, AirPort Express support WPA2.
When you set up most routers (stand-alone routers and modem routers), you are asked to provide a pass phrase that the router uses to generate several keys.Some routers and modem routers now come with a function called Quick Security Setup (or QSS) that automatically issues you a key when you press a button on the router.
Be sure to keep a hard copy and a digital copy of your network security key and pass phrase. You can recover a lost network key or reset it on your router, but these sometimes entail setting up your network again.

 

Your administrative password, which controls your wireless network.
