FRITZ!OS Version

System / Update / FRITZ!OS Version

AVM provides updates of the FRITZ!OS of your FRITZ!Box for free downloading over the internet. FRITZ!OS is the software that controls all of the FRITZ!Box functions. FRITZ!OS Updates contain further developments of existing FRITZ!Box functions and often also introduce new functions for your FRITZ!Box.

Finding New FRITZ!OS and Transferring It to the FRITZ!Box

  1. Click the "Find New FRITZ!OS" button.

    The FRITZ!Box checks whether an update for FRITZ!OS is available. If an update is found, the "Start Update Now" button appears.

  2. Click "Start Update Now".

    The "Info" LED on the FRITZ!Box starts flashing and the new FRITZ!OS is transmitted to the FRITZ!Box. The update is complete when the "Info" LED stops flashing.

Important: Do not disconnect FRITZ!Box from the computer during an update, and do not interrupt the power supply to the FRITZ!Box! If the update is interrupted, your FRITZ!Box may be irreparably damaged!

Once the update is complete, you will be automatically redirected to the FRITZ!Box "Overview" page.
