Deny Non-Encrypted Data-- Select this checkbox if you want to deny
all received data that is not encrypted. When this checkbox is selected,
any packet received that is not encrypted using one of the four WEP
Encryption keys listed above will be dropped. When this checkbox is not
selected, unencrypted packets will be accepted and/or forwarded.
Warning: You should always select this checkbox if WEP is enabled in
any form. If disabled, clients without WEP can access your network!
Use n-bit WEP Keys-- Select either 64-bit (silver) or 128-bit (gold)
encryption keys. The higher bit count provides somewhat higher security.
AES(Advanced Encryption Standard)—If you want more secured
encryption than n-bit WEP, you can choose this option with which 16
character string's keys are supportable for Atheros based untis.
Static WEP Encryption Keys-- If you use static encryption keys, you
must enter each key in the Static WEP Encryption Keys fields. Note that
these keys must be entered identically on each access point/station and
Secure Data Mode unit in the network.
Encrypt Data Transmission Using Key n-- Enter the key number that
should be used to encrypt data on this interface. Note that you can
receive using any key, but will generally always transmit using a single
key. Unicast transmissions to an 802.1x station with dynamic keys will
use that's station's dynamic key, but all broadcasts, multicasts, and other
unicasts will be encrypted using the key identified in this field.
