Performing a FRITZ!OS Update Manually
Overview
The FRITZ!Box works with its own operating system FRITZ!OS.
AVM regularly makes new versions of FRITZ!OS available for your
FRITZ!Box, free of charge. Updates contain further developments and
often new features.
In some cases it is not possible to perform an automatic update, or an
update via the “Mesh Overview” or wizard. Then you have the option of
performing a manual update with a FRITZ!OS file that is already saved
on your computer’s hard drive, or on a storage medium connected to
the computer, for instance a USB stick. No internet connection is need-
ed for this update.
Always install the latest FRITZ!OS version on all FRITZ! products in
your FRITZ!Box home network. This keeps your FRITZ! products up to
date and ensures optimum synchronization of all devices in your home
network.
Instructions: Updating FRITZ!OS without an Internet Connection
Do not clear the connection between FRITZ!Box and the computer dur-
ing a FRITZ!OS update, and do not unplug any power cords. Interrupt-
ing a FRITZ!OS update could damage your FRITZ!Box.
1. On a computer with an internet connection, enter the following
address in the browser: download.avm.de
2. Navigate through the following folders: fritzbox > your
FRITZ!Box model > deutschland > fritz.os.
The complete model name of your FRITZ!Box is shown in the
user interface on the Overview page and on the type label on the
outside of the housing.
3. Download the file with the file extension .image and save it to a
location which you can access via the FRITZ!Box user interface,
for instance, to a USB storage medium.
