Fresh from Development

This FRITZ! Lab contains new functions fresh from the development team and gives a preview of upcoming FRITZ!OS features in the next major update. It also contains the latest developments in the areas of security and energy efficiency.

The FRITZ! Lab launched adds additional control functions to the home network, increases fallback protection for the internet connection, and optimizes the smart home. For the first time, this FRITZ!

Installation on the FRITZ!Box

You're not using the current FRITZ!OS in your FRITZ!Box yet? Then first update FRITZ!OS to the latest release version. Here we tell you how this works.

Once your FRITZ!Box has the latest FRITZ!OS installed you can start installation of the lab version.

Read and confirm the information displayed.
Click on ‘Download’ and save the file on your computer.
Unpack the lab file (*.zip).
Use the FRITZ!Box user interface to install the update:
Select the ‘System / Update’ menu.
Select the ‘FRITZ!OS file’ tab. Back up the settings of your FRITZ!Box.
Select the lab version that matches your FRITZ!Box model (e.g. C:\Documents and Settings\Username\Desktop\FRITZ!Box-xxxxxx-Lab.image).
Click on ‘Start Update’.
Follow the instructions displayed on the screen.

During the update process the ‘Info’ LED on your FRITZ!Box will flash. The LED goes out once the update is complete. Please be patient, as this process may take several minutes. As soon as the update has been completed, the FRITZ!Box restarts and is then ready for operation.
