Restoring the FRITZ!OS of your FRITZ!WLAN Repeater

The recovery tool is used to restore your FRITZ!WLAN Repeater to working order. The recovery tool resets the repeater 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 repeater model, then to the subfolder "other", and then to the folder "recover".
  3. Download the recovery tool for your repeater to your computer. It has the file extension ".exe".

2 Connecting the computer with the repeater

  1. Use the network cable included with delivery to connect the computer directly to the "LAN" port on the repeater.
  2. Clear all other connections between your repeater 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:

    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.wlan_repeater...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!WLAN Repeater successfully restored!", then the recovery process was successful.
