Media Access Control (MAC) address is a unique identifier assigned to each network adapter of any device.  A Linksys router has a Wireless MAC Filter feature that lets you permit or prevent users from accessing the wireless network by blocking or allowing the MAC addresses of computers or devices.

This article will guide you on how to configure the Wireless MAC Filter feature on a Linksys router’s web-based setup page to permit or prevent the wireless devices connected to your Linksys Wireless-N Range Extenders (RE1000 and RE3000W).  To know how, perform the following steps:

         i.   Obtain the range extender's MAC address
         ii.  Obtain the Global and Virtual MAC addresses
         iii. Set up Wireless MAC Filter

NOTE:  The steps below will apply to Linksys RE1000 and RE3000W v1 ONLY.  The first two (2) steps above are done on the range extender’s web-based setup page while the last one (1) is on the router’s web-based setup page.

Obtain the range extender's MAC address

Step 1:
Access the range extender’s web-based setup page.  For instructions, click here.

Step 2:
Click Status > Device Info and check the Extender Mac Address values.

Obtain the Global and Virtual MAC addresses

The Global and Virtual MAC addresses are obtained from all wireless computers or devices that are connected to the range extender.

NOTE:  A MacBook®’s Global and Virtual MAC addresses are used in this example.

Step 1:
On the range extender’s web-based setup page, click Status > WLAN Statistics.

Step 2:
Click  at the bottom of the page.

Step 3:
On the Wireless Clients Table window, take note of the values under the Global and Virtual MAC section.

After getting the range extender’s MAC address and your device’s Global and Virtual MAC addresses, you can start setting up the router’s Wireless MAC Filter.  To do this, follow the steps below:
