Restricting wireless access to known devices (MAC address filter)

The FRITZ!Box's wireless network (WiFi) is already protected against unauthorized access by individual wireless security settings in its factory settings. With the FRITZ!Box's MAC address filter you can also specify which wireless devices are allowed to connect to the FRITZ!Box.

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 does not provide sufficient protection from undesired access and can only be used as a complementary measure.

Requirements / Restrictions

  • The MAC address filter does not restrict login to the wireless guest access.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Enabling the MAC address filter

  1. Click "Wireless" ("WLAN") in the FRITZ!Box 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 LAN access" section.
  4. Click "Apply" to save the settings.

Now only wireless devices listed in the "Restricting wireless LAN access" section are allowed to connect to the FRITZ!Box's wireless network.

2 Adding a new wireless device

To add the MAC address of a new wireless device to the list of "Known Wireless LAN Devices", you can either temporarily disable the MAC address filter to automatically add the MAC address of the FRITZ!Box, or enter the MAC address manually:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Security" in the "Wireless" ("WLAN") menu.
  3. Click "Add Wireless Device" in the "Restricting wireless LAN access" section.
  4. Enter the MAC address of the wireless device.
  5. Click "OK" and then "Apply" to save the settings.
