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.
2.
In the Advanced Wireless Settings screen, click
Setup Access List
to display the Wireless
Card Access List.
Figure 11.
3.
Click

to add a wireless device to the wireless access control list. The Wireless Card
Access Setup screen opens and displays a list of currently active wireless cards and their
Ethernet MAC addresses.
