1. Call up download.avm.de/fritzbox/ in your web browser.
2. Switch to the folder for your FRITZ!Box model, then to the subfolder "deutschland", and then to the folder "recover".

   Note:The complete model name of your FRITZ!Box is shown in the FRITZ!Box user interface on the "Overview" page and is also printed on the sticker on the underside of the device.

2. Clear all other connections between your FRITZ!Box and network devices or USB devices.

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 FRITZ!Box internet connection 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:
