The WPA encrypts each frame transmitted from the radio using the key, which either PSK
(Pre-Shared Key) entered manually in this field below or automatically negotiated via 802.1x
authentication.
Available parameters are listed below:
Item Description
WPA Algorithms Select TKIP, AES or TKIP/AES as the algorithm for WPA.
Key Renewal Interval WPA uses shared key for authentication to the network.
However, normal network operations use a different
encryption key that is randomly generated. This randomly
generated key that is periodically replaced. Enter the renewal
security time (seconds) in the column. Smaller interval leads
to greater security but lower performance. Default is 3600
seconds. Set 0 to disable re-key.
PMK Cache Period Set the expire time of WPA2 PMK (Pairwise master key)
cache. PMK Cache manages the list from the BSSIDs in the
associated SSID with which it has pre-authenticated.
Pre-Authentication Enables a station to authenticate to multiple APs for roaming
securer and faster. With the pre-authentication procedure
defined in IEEE 802.11i specification, the
pre-four-way-handshake can reduce handoff delay
perceivable by a mobile node. It makes roaming faster and
more secure. (Only valid in WPA2)
Enable - Enable IEEE 802.1X Pre-Authentication.
Disable - Disable IEEE 802.1X Pre-Authentication.
