Restricting wireless access to known devices (MAC address filter)

FRITZ!Powerline has its own MAC address filter that you can use to specify which wireless devices are allowed to connect to the powerline adapter. Since wireless devices transmit their unencrypted MAC address in every data packet, attackers can easily determine a MAC address that is allowed to connect. Therefore, the MAC address filter alone does not provide sufficient protection from undesired access and is only suitable as a supplementary measure for secure wireless encryption.

Requirements / Restrictions

  • The MAC address filter does not apply to wireless devices that use FRITZ!Powerline's wireless guest access.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for FRITZ!Powerline.

1 Enabling the MAC address filter

  1. Click "Wireless" ("WLAN") in the FRITZ!Powerline user interface.
  2. Click "Security" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Do not allow any new wireless devices" in the "Restricting Wireless Access" section.
  4. Click "Apply" to save the settings.

Now only wireless devices listed under "Restricting Wireless Access" are allowed to connect to FRITZ!Powerline's wireless network.
