LABEL DESCRIPTION
ReAuthentication
Timer (in
seconds) Specify how often wireless stations have to reenter usernames and passwords in
order to stay connected. Enter a time interval between 10 and 9999 seconds. The
default time interval is 1800 seconds (30 minutes).
)
If wireless station authentication is done
using a RADIUS server, the reauthentication
timer on the RADIUS server has priority.
Idle Timeout The HomeSafe automatically disconnects a wireless station from the wired network
after a period of inactivity. The wireless station needs to enter the username and
password again before access to the wired network is allowed. The default time
interval is 3600 seconds (or 1 hour).
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 HomeSafe 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 HomeSafe.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the HomeSafe.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN
devices to associate with the HomeSafe. The transmission rate of your HomeSafe
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
HomeSafe 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.

7.9 802.1x 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 HomeSafe (authenticate up to 32 users) or an external RADIUS
server for an unlimited number of users.
