Changed Wi-Fi settings cannot be saved

Changes to the Wi-Fi settings of the FRITZ!Box 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.

Cause

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

Adjusting the web browser settings

If you are using Google Chrome or Mozilla Firefox, configure an exception for the FRITZ!Box in the web browser's pop-up blocker:

  • Google Chrome
    1. Click the (Customize and control Google Chrome) button on the top right of Chrome.
    2. Click "Settings" and then "Extensions".
    3. Click "Options" for the pop-up blocker you are using.
    4. Enter fritz.box as an exception and close the "Extensions" window.
  • Mozilla Firefox
    1. Click the (Open menu) button on the top right of Firefox.
    2. Click "Options”.
    3. Click "Privacy & Security" in the menu on the top left of the screen.
    4. In the section "Permissions", click the "Exceptions" button next to the option "Block pop-up windows".
    5. Enter fritz.box under "Address of website".
    6. Click "Allow" and then "Save changes".
