FRITZ!Box 4040 Service - Knowledge Base
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.
The "Online Update" function allows you to install the latest FRITZ!OS for your FRITZ!Box quickly and easily. If you cannot use the "online update" function, for example because the FRITZ!Box is not connected to the Internet, you can update manually.
1 Installing the latest FRITZ!OS
- Click "System" in the FRITZ!Box user interface.
- Click "Update" in the "System" menu.
- Click the "Find New FRITZ!OS" button.
- If a new version is available, then the "Start Update Now" button is displayed. Click the button to start the update.
Now the latest FRITZ!OS is installed. If you enable the option "Notify me about new versions of FRITZ!OS and install new versions automatically" under "System > Update > Auto-Update" in the user interface, then future updates will be installed automatically.
