Chapter 16: 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.
The following sections describe how to use MAC address filtering on the AT-TQ2403 Management
Software:

MAC address or prevent access to the stations listed.
