Wired Equivalent Privacy, or WEP, is a security protocol for wireless networks. WEP requires a Wireless Encryption Key to access the wireless network. The key is encrypted and stored on the router and on any computers that are connected to the router. Connections that do not send the correct WEP key are denied by the router. The secure connection encrypts data sent over the network and provides privacy equivalent to that of a wired network–thus the name Wired Equivalent Privacy.

Log on to the router's administrative interface with the Administrator user ID and password.
Click the "Wireless Settings" link from the main page of the interface and scroll to the "Security Encryption (WEP) Key section. The Wireless Encryption Key is listed in the field labeled "Key 1." The WEP key will be an alpha-numeric string.
