Besides the online update, the firmware of the FRITZ!Box can also be updated offline using a firmware file.
Download the new firmware file from the Internet to your computer. The currently installed firmware version is displayed on the "Firmware File" settings page. The version number of the downloaded firmware is included in the file name. Perform an update only if the downloaded firmware is a newer version.
Caution: Do not disconnect FRITZ!Box from the computer during a firmware update, and do not unplug the power cord! If the firmware update is interrupted, your FRITZ!Box may become unusable!
