# About a Security Key for a Wireless LAN

A security key is a security protocol for a wireless LAN that encrypts data transmitted on the wireless LAN. 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 wireless LAN access point and a computer, to communicate with each other on the wireless LAN.
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.

1. Click (Start) and Control Panel.

1. Click Network and Internet and Network and Sharing Center.

1. Click Manage wireless networks in the left pane.

1. Right-click the desired network in the Networks you can view and modify list, and then click Properties.

1. Click the Security tab.

1. Enter a security key in the Network security key field and click OK.
