System Configuration
Note: Although a WEP static key is not needed for WEP over 802.1X,
WPA over 802.1X, and WPA PSK modes, you must enable WEP
encryption through the web or CLI in order to enable all types of
encryption in the access point.
Wired Equivalent Privacy (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
