Restrict Wireless Access by MAC Address
You can set up a list of computers and wireless devices that are allowed to join the wireless
network. This list is based on the unique MAC address of each computer and device.
Each network device has a MAC address, which is a 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). Typically, the MAC address is on the label of the wireless
card or network interface device. If you do not have access to the label, you can display the
MAC address using the network configuration utilities of the computer. You might also find
the MAC addresses in the Attached Devices screen.
 To restrict access based on MAC addresses:
1. Select Advanced > Wireless Setting and click Set Up Access List to display the
Wireless Card Access List screen.
2. Click Add 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.
3. If the computer or device you want is in the Available Wireless Cards list, select that radio
button; otherwise, type a name and the MAC address. You can usually find the MAC
address on the bottom of the wireless device.
Tip: You can copy and paste the MAC addresses from the router’s Attached
Devices screen into the MAC Address field of this screen. To do this, use
each wireless computer to join the wireless network. The computer
should then appear in the Attached Devices screen.
