LABEL
DESCRIPTION
WPA Compatible
This check box is available only when you select
WPA2-PSK
or
WPA2
in the
Security Mode
field.
Select the check box to have both WPA2 and WPA wireless clients be able to
communicate with the NBG334W even when the NBG334W is using WPA2-PSK
or WPA2.
ReAuthentication
Timer (in seconds)
Specify how often wireless stations have to resend 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).
Note: If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server
has priority.
Idle Timeout
The NBG334W 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).
Group Key Update
Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA-PSK/
WPA2-PSK
key management) or RADIUS
server (if using
WPA/WPA2
key
management) sends a new group key out to all clients. The re-keying process is
the WPA/WPA2 equivalent of automatically changing the WEP key for an AP and
all stations in a WLAN on a periodic basis. Setting of the
Group Key Update
Timer
is also supported in
WPA-PSK/WPA2-PSK
mode. The NBG334W default
is
1800
seconds (30 minutes).
