Updating FRITZ!OS

FRITZ!OS is the software stored in the FRITZ!Box that controls all of its functions. We make new versions of FRITZ!OS available on a regular basis that enhance and add new functions to your FRITZ!Box.

With the "Online Update" function you can install the latest FRITZ!OS for your FRITZ!Box quickly and easily.
If you cannot use the "online update" function, for example when the FRITZ!Box is not connected to the Internet, update the firmware manually.

1 Installing the latest FRITZ!OS

  2. Click "Update" in the "System" menu.
  3. Click the "Find New FRITZ!OS" button.
  4. If a new version is found, then the "Start Update Now" button is displayed. Click the button to start the update.

The "Info" LED flashes while the update is being transmitted to the repeater.
