Changed Wi-Fi settings cannot be saved

Changes to the Wi-Fi settings of the FRITZ!Powerline device cannot be saved. For example, a new network key cannot be adopted or the MAC address filter cannot be disabled. When you click "Apply", the previous settings are displayed again.


  • The web browser settings prevent the pop-up window displaying the changed Wi-Fi settings for you to print out from opening automatically. The FRITZ!Powerline device does not save the new settings for security reasons.
