FRITZ!Box 4020 Serwis

Changed wireless settings cannot be saved

Changes to the wireless settings of the FRITZ!Box cannot be saved. This means that a new wireless key cannot be adopted or the MAC address filter cannot be disabled, for example. When you click "Apply", the previous settings are displayed again.


  • Due to the web browser settings, the pop-up window displaying the changed wireless settings so you can print them is prevented from opening automatically. The FRITZ!Box does not save the new settings for security reasons.
