Determining the FRITZ!Box's MAC address

A MAC address (Media Access Control address) serves to unambiguously identify a device in the network.
The MAC address by which the FRITZ!Box can be reached by another network device (such as a computer) depends on which network interface (LAN, wireless LAN (WiFi)) the network device is using to communicate with the FRITZ!Box.

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

  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Make note of the MAC address listed in the section "2.4-GHz frequency band" or "5-GHz frequency band". If the MAC address is not displayed, enable the Advanced View first.
