WEP provides a basic level of security, preventing unauthorized access to
the network, and encrypting data transmitted between wireless clients and
the VAP. 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) and WPA2 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. All clients share the same keys, which are
used for user authentication and data encryption. Up to four keys can be
specified.
