Access List screen. You can restrict access to your network to specific devices based on their 
MAC address. 
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. On the Advanced Wireless Settings screen, 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. To do this, use each 
wireless computer to join the wireless network. The computer should 
then appear in the Attached Devices screen.
4. Click Add to add this wireless device to the Wireless Card Access List. The screen changes 
back to the list screen. 
5. Add each computer or device you want to allow to connect wirelessly.
6. Select the Turn Access Control On check box.
