 (WEP) 

WEP provides a basic level of security, preventing unauthorized access to the 
network, and encrypting data transmitted between wireless clients and the access 
point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric 
strings) that are manually distributed to all clients that want to use the network.

WEP is the security protocol initially specified in the IEEE 802.11 standard for 
wireless communications. Unfortunately, WEP has been found to be seriously 
flawed and cannot be recommended for a high level of network security. For 
more robust wireless security, the access point provides Wi-Fi Protected Access 
(WPA) for improved data encryption and user authentication.

Setting up shared keys enables the basic IEEE 802.11 Wired Equivalent Privacy 
(WEP) on the access point to prevent unauthorized access to the network.

If you choose to use WEP shared keys instead of an open system, be sure to 
define at least one static WEP key for user authentication and data encryption. 
Also, be sure that the WEP shared keys are the same for each client in the wireless 
network.
