Updating FRITZ!OS

FRITZ!OS is the operating system of the FRITZ!Box. We provide updates on a regular basis that add new functions to our FRITZ! products and optimize the software so that it is compatible with the latest technology.

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.
