encryption cipher suite is set to TKIP, the unicast encryption cipher
(TKIP or AES-CCMP) is negotiated for each client. The access point
advertises it’s supported encryption ciphers in beacon frames and
probe responses. WPA and WPA2 clients select the cipher they support
and return the choice in the association request to the access point. For
mixed-mode operation, the cipher used for broadcast frames is always
TKIP. WEP encryption is not allowed.

COMMAND USAGE
â—† Selecting a security method using the auth command, automatically
enables data encryption (WEP, TKIP, or AES-CCMP) for the VAP. Only
use this command when using WEP encryption with an Open System.
â—† Encryption is implemented in this device to prevent unauthorized
access to your wireless network. For more secure data transmissions,
enable encryption by selecting a security method using the auth
command, or by using the encryption command when using WEP
encryption only.
â—† The encryption settings must be the same on each client in your
wireless network.
â—† Note that encryption protects data transmitted between wireless nodes,
but does not protect any transmissions over your wired network or over
the Internet.
