v1.1, May 2008
The available settings in this screen are:
• Enable SSID Broadcast . Clear this check box to disable broadcast of the SSID, so that
only devices that know the correct SSID can connect. Disabling SSID broadcast nullifies
the wireless network discovery feature of some products such as Windows XP.
• Enable Wireless Router Radio . If you disable the wireless router radio, wireless devices
cannot connect to the Wireless-G Router. If you will not be using your wireless network
for a period of time, you can clear this check box and disable all wireless connectivity.
• Enable WMM . Clear this check box to disable WMM. Disabling WMM turns off the
wireless prioritization scheme. Note that wireless clients must also support WMM to take
advantage of this feature.
• Wireless Card Access List . For information about this list, see “Restricting Wireless
Access by MAC Address” on page 2-11 .

Restricting Wireless Access by MAC Address
When a Wireless Card Access List is configured and enabled, the router checks the MAC address
of any wireless device attempting a connection and allows only connections to computers
identified on the trusted computers list.
The Wireless Card Access List displays a list of wireless computers that you allow to connect to
the router based on their MAC addresses. These wireless computers must also have the correct
SSID and wireless security settings to access the wireless router.
The MAC address is a network device’s unique 12-character physical address, containing the
hexadecimal characters 0–9, a–f, or A–F only, and separated by colons (for example,
00:09:AB:CD:EF:01). It can usually be found on the bottom of the wireless card or network
interface device. If you do not have access to the physical label, you can display the MAC address
using the network configuration utilities of the computer. In WindowsXP, for example, typing the
ipconfig/all
command in an MSDOS command prompt window displays the MAC address as
Physical Address. You might also find the MAC addresses in the router’s Attached Devices screen.
To restrict access based on MAC addresses:
1. Select Wireless Settings under Advanced in the main menu.
Note: The Fragmentation Threshold, CTS/RTS Threshold, and Preamble Mode
options are reserved for wireless testing and advanced configuration only. Do
not change these settings.
