Controlling access by MAC address filtering

A Media Access Control (MAC) address is a hardware address that uniquely identifies each node of a network. All IEEE 802 network devices share a common 48-bit MAC address format, usually displayed as a string of 12 hexadecimal digits separated by colons, for example FE:DC:BA:09:87:65.

Each wireless network interface card (NIC) used by a wireless client has a unique MAC address.

You can control client access to your wireless network by switching on MAC filtering and specifying a list of approved MAC addresses. When MAC filtering is on, only clients with a listed MAC address can access the network.

Navigating to MAC filtering settings

To enable filtering by MAC address, click Advanced > MAC Filtering on the Administration Web page. The Configure MAC filtering of client stations screen opens. Update the boxes as described in the following section.
