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 wireless card or 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). The MAC address is typically on a
label on the wireless card or 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 Settings, and click the Setup Access List to display the
Wireless Card Access List.
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 Attached Devices
screen into the MAC Address field of this screen. Each computer that
joins the wireless network is listed in the Attached Devices screen.

Click Add to add this wireless device to the Wireless Card Access List. The screen changes
back to the list screen.
