LABEL DESCRIPTION
WPA Group Key
Update Timer The WPA Group Key Update Timer is the rate at which the AP (if using WPA-PSK
key management) or RADIUS server (if using WPA key management) sends a new
group key out to all clients. The re-keying process is the WPA equivalent of
automatically changing the WEP key for an AP and all stations in a WLAN on a
periodic basis. Setting of the WPA Group Key Update Timer is also supported in
WPA-PSK mode. The Prestige default is 1800 seconds (30 minutes).
Preamble Select a preamble type from the drop-down list menu. Choices are Long, Short or
Dynamic. The default setting is Long. See the section on preamble for more
information.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the Prestige.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the Prestige.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices
to associate with the Prestige. The transmission rate of your Prestige might be
reduced.
Max. Frame Burst Enable Maximum Frame Burst to help eliminate collisions in mixed-mode networks
(networks with both IEEE 802.11g and IEEE 802.11b traffic) and enhance the
performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks.
Maximum Frame Burst sets the maximum time, in microseconds, that the Prestige
transmits IEEE 802.11g wireless traffic only.
Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800
recommended). Enter 0 to disable this feature. The default is 650.

8.9 802.1x Overview
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations
and encryption key management. Authentication can be done using the local user database internal to the
Prestige (authenticate up to 32 users) or an external RADIUS server for an unlimited number of users.
