Chapter 7 Wireless LAN

NBG420N User’s Guide

The following table describes the labels in this screen.

7.5.4 WPA/WPA2

Click Network > Wireless LAN to display the General screen. Select WPA or WPA2 from

the Security Mode list.

Table 32 Network > Wireless LAN > General: WPA-PSK/WPA2-PSK

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 NBG420N even when the NBG420N is using WPA2-PSK or

WPA2.

Pre-Shared Key The encryption mechanisms used for WPA/WPA2 and WPA-PSK/WPA2-PSK are

the same. The only difference between the two is that WPA-PSK/WPA2-PSK uses

a simple common password, instead of user-specific credentials.

Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including

spaces and symbols).

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 NBG420N 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 default is 1800

seconds (30 minutes).
