MAC Address Filtering

MAC Address Filtering refers to a security access control methodology, in which the 48-bit address assigned to each network card is used to determine access to the network. In most Wi-Fi access points and routers this feature is disabled by default. This feature relys on a white list of clients (based on their MAC address) created by the owner of the Wi-Fi network. When this feature is enabled it checks each request to join the Wi-Fi network and compares the client MAC address to the white list. If the client is on the list, access is allowed; if not, then access is denied.
