WPS Settings
These options are available if the settings in the Wireless Settings screen are compatible with 
WPS. 

Router’s PIN. The PIN is displayed so that you can use it to configure the router through 

WPS (Wi-Fi Protected Setup). It is also displayed on the router’s label.

Disable Router’s PIN. If the router’s PIN is disabled, you cannot configure the router’s 

wireless settings with WPS. However, if your settings are already configured, you can still 
add WPS-enabled wireless clients. The router might disable the PIN if it detects 
suspicious attempts to break into your wireless settings; this can happen if the check box 
is selected. You can enable the PIN by clearing the check box and clicking 

Apply. 

Keep Existing Wireless Settings. This check box is automatically selected after WPS is 

enabled to prevent unwanted settings changes, and is also selected if you have already 
specified wireless security settings or your SSID without using WPS. When this check 
box is not selected, adding a new wireless client using the push button or the Add WPS 
Client screen (see 

router’s SSID and security passphrase. You might need to clear it if you are using certain 
registrars, such as for a Windows Vista PC, to configure the router through WPS.

Wireless Card Access List
You can use this feature to restrict access by MAC address as described in the following 
section.

Restrict Wireless Access by MAC Address

MAC address filtering adds an obstacle against unwanted access to your network by the 
general public. However, because your trusted MAC addresses appear in your wireless 
transmissions, an intruder can read them and impersonate them. Do not rely on MAC 
address filtering alone to secure your network.

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 

 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.
