The following table describes the labels in this screen.
7.3 MAC Filter
The MAC filter screen allows you to configure the NBG4115 to give exclusive
access to up to 16 devices (Allow) or exclude up to 16 devices from accessing the
NBG4115 (Deny). Every Ethernet device has a unique MAC (Media Access Control)
address. The MAC address is assigned at the factory and consists of six pairs of
hexadecimal characters, for example, 00:A0:C5:00:00:02. You need to know the
MAC address of the devices to configure this screen.
Table 29 Network > Wireless LAN > General: WPA-PSK/WPA2-PSK
LABEL DESCRIPTION
WPA
Compatible This check box is available only when you select WPA2-PSK in the
Security Mode field.
Select the check box to have both WPA2 and WPA wireless clients be
able to communicate with the NBG4115 even when the NBG4115 is
using WPA2-PSK.
Pre-Shared Key WPA-PSK/WPA2-PSK uses a simple common password for
authentication.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters
(including spaces and symbols).
Type a pre-shared key less than 64 case-sensitive HEX characters ("0-
9", "A-F").
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).
