About a Security Key for Wi-Fi(R) (Wireless LAN)
A security key is a security protocol for Wi-Fi that encrypts data transmitted on Wi-Fi. It is also referred to as an encryption
key or a WEP (Wired Equivalent Privacy) key.
The security key allows wireless devices that have the same key, such as a Wi-Fi access point and a computer, to
communicate with each other on Wi-Fi.
The security key is assigned to each access point by default. (Make sure the default security key has been changed to protect
data from unauthorized use.) If you cannot find the default security key, refer to the manual that came with your access point.
If you enter a wrong security key, follow these steps to re-enter the security key.
