Restoring the FRITZ!OS of the FRITZ!Smart Gateway

The recovery program can be used to restore your FRITZ!Smart Gateway to working order. The recovery program resets the FRITZ!Smart Gateway to its factory settings and deletes all of the settings that could be preventing it from working correctly.

Requirements

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

1 Downloading the recovery program

  3. Download the recovery program for your FRITZ!Smart Gateway to the computer; it has the file extension ".exe".

2 Connecting the computer with the FRITZ!Smart Gateway

  1. Use the network cable included with delivery to connect the computer directly to the LAN port on the FRITZ!Smart Gateway.

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 re-establish the internet connection until the firewall is restarted.
  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:

4 Running the recovery program

  1. Run the file "FRITZ.Smart_Gateway[...].exe" and click "Next".

  3. If the program displays an error message such as "Recovery failed due to an error", run the program again. If executing the recovery program fails after several attempts, run the program on a different computer.
    • If the recovery program displays the message "Complete - FRITZ!Smart Gateway successfully restored!", recovery was successful.
