Restoring the FRITZ!OS of FRITZ!Powerline

The recovery program can be used to restore the FRITZ!Powerline adapter to working order. The recovery program resets the FRITZ!Powerline adapter to its factory settings and deletes all of the settings that are preventing it from working correctly.


  • Windows 11 / 10 / 8 / 7 is installed on the computer.

1 Downloading the recovery program

  1. Call up in your web browser.
  2. Switch to the folder for your FRITZ!Powerline model, then to the subfolder "deutschland" or "other", and then to the folder "recover".
  3. Download the recovery program for your FRITZ!Powerline adapter to your computer. It has the file extension ".exe".

2 Connecting the FRITZ!Powerline adapter with the computer

  1. Use the network cable included with delivery to connect the computer directly to the LAN port on FRITZ!Powerline.
  2. Clear all other connections between your FRITZ!Powerline and other network devices.

3 Disabling firewalls

ATTENTION!Only disable firewalls to run the recovery program and re-enable them before connecting to the internet. This software protects your computer from attacks from the internet and prevents other threats (for example computer viruses) from being executed.

  1. Disconnect the computer from the internet and do not reconnect it until the firewall is started.
  2. Configure all firewalls on your computer (for example, Zone Alarm, Norton Security) so that they are not automatically re-enabled when your computer restarts.
  3. Close any active firewall applications.
  4. Disable the Windows firewall:

    Windows 11 / 10

    1. In the Windows task bar, click (Start) and then "Windows Security" or "All apps" and then "Windows Security".
    2. Click "Firewall & network protection" in the menu "Windows Security".
    3. Click on the active network (normally "Private network").
    4. Disable the Microsoft Defender Firewall.

    Windows 8

    1. Press the keyboard shortcut Windows key + X and select "Control Panel" from the context menu.
    2. Click "System and Security" and then "Windows Firewall".
    3. Disable the Windows firewall.

    Windows 7

    1. Click "Start" and "Settings" (if available).
    2. Control Panel > (System and Security >) Windows Firewall
    3. Disable the Windows firewall.
  1. Run the file "fritz.powerline...recover-image.exe" and click "Next".
  2. Follow the instructions.
  3. If you are asked to do so, select the network adapter that the FRITZ!Powerline adapter is connected to. Normally the correct network adapter is already selected.
  4. If the program displays an error message such as "Recovery failed due to an error", run it again. If recovery fails after several attempts, run the recovery program on a different computer.
    • If the recovery program displays the message "Complete - FRITZ!Powerline successfully restored!", recovery was successful.
