Restoring the FRITZ!OS of your FRITZ!Powerline

The recovery tool is used to restore your FRITZ!Powerline adapter to working order. The recovery tool resets the FRITZ!Powerline adapter to its factory settings and deletes all of the settings that are preventing it from functioning properly.


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

1 Downloading the recovery tool

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

2 Connecting FRITZ!Powerline 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 when applying the recovery tool and re-enable them before establishing an internet connection. 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 you have restarted your firewall.
  2. Configure all firewalls on your computer (e.g. ZoneAlarm, 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 10

    1. Click "Start" and then "Settings" in the Windows task bar.
    2. Click "Network and Internet" and then "Windows Firewall" in the "Settings" menu.
    3. Disable the Windows 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.

4 Applying the recovery tool

  1. Run the file "fritz.powerline...recover-image.exe" and click "Next".
  2. Follow the instructions.
  3. If the tool displays an error message such as "Recovery failed due to an error", run it again. If recovery fails after several attempts, run the recovery tool on a different computer.
    • If the recovery tool displays the message "Complete - FRITZ!Powerline successfully restored!", then the recovery process was successful.
