AVM FRITZ!Box 5530 Fiber (FRITZ!OS) at a glance
The FRITZ!Box 5530 Fiber is a router from AVM for fibre connections. It provides internet access, supplies the Wi-Fi, connects telephones and manages the home or small office network through the FRITZ!OS interface. Administrators use it in practices, law firms and branch offices where a connection should run with little supervision.
AVM publishes the firmware for each device on an open download server and announces changes in its update news. Besides feature updates there are security fixes, which can also be installed by the automatic update function. The levels range from no automatic updating to all updates.
During an update the internet connection is briefly interrupted and calls in progress end. A backup of the settings is advisable beforehand. For devices at remote locations the update should take place at a time when someone is reachable on site.
