New features for the FRITZ!Box: New design for FRITZ!OS 6.50, with better overview of the home network and over 120 innovations

The latest update offers a redesigned user interface at, optimized for smartphones, tablets and notebooks. In the browser it adjusts flexibly to the different display sizes. The user interface also received a fresh new look. The menu items and their arrangement remain familiar to users.

The extensive home network overview of all connected devices is also new. These include all wireless, LAN, powerline, DECT, smart home and USB devices. At a single glance users can see whether their connected FRITZ! products are equipped with the latest version of FRITZ!OS. You can start updates directly from here.

With the new FRITZ!OS you can also use helpful analyses of your wireless LAN environment. Under "Wireless / Radio Channel" the loading of the radio channel currently in use is shown over time for the 2.4-GHz and the 5-GHz frequency band. The lower the loading of the radio channel, the better the potential data throughput there.

Now there is an option for granting guest access to the wireless LAN or LAN only after consent to the FRITZ!Box owner's terms of use. The guest is taken first to a captive portal to signal consent. Without confirming this page, you cannot connect to the Internet.

News for parental controls: Tickets can be issued for each device to extend surfing time by 45 minutes. When online time has been exhausted, tickets can be redeemed on the Information page on blocked Internet use in the browser.
By going to with any network device, you can view the device's settings for Internet use and the amount of online time already used on the current day.

If there are problems with network access or Internet telephony, the FRITZ!Box notifies the user by lighting the "Info" LED red. The start page of the user interface displays more precise information about the reason for the disruption.

You can also benefit from new options for telephony: For instance, unwanted calls can now be blocked by setting up a blacklist in the telephone book.

There are plenty of new features for DECT as well: With three new start screens ("Answering machine", "FRITZ!Box" and "New calls"), now the FRITZ!Fon can be adapted even more flexibly to your needs. This makes important information and events easier to view and access. Tip: Update the software on FRITZ!Fon and press the "MENU" key twice.

A lot has been done for the smart home features as well: Now FRITZ!Fon supports door intercom systems with video function: When the doorbell rings, you can see every visitor right on your FRITZ!Fon. Support for the Comet DECT radiator thermostat opens up all kinds of new possibilities. The device is seamlessly integrated into the user interface of the new FRITZ!OS, allowing you to control the temperature at home and save costs through energy efficient heating.

Along with heating, now an advanced group function can be used to switch one or more actuators (FRITZ!DECT 200, FRITZ!Powerline 546E) on or off by temperature.
Here the actuator itself, for instance a FRITZ!DECT 200 or FRITZ!DECT Repeater 100 serves as the temperature sensor. More innovations in the smart home area include options for sunrise/sunset switching, up to 140 freely selectable switching points for the "according to schedule" option, and the dispatch of consumption data as an attachment to a push mail from FRITZ!DECT 200 and FRITZ!Powerline 546E.

Since AVM also optimizes the security of the entire FRITZ! family with every new FRITZ!OS, it is advisable for every user to perform the update. This way All-IP connections can be better protected from unauthorized Internet calls from the home network ("Telephony / Telephone Numbers / Line Settings"). The firewall can be operated in stealth mode to prevent ping queries. TLS security has been improved and port 25 received a new filter to block the unsecured e-mail dispatch.

This benefits not only Telekom and Vodafone customers, but also any users of "other providers" who use a single password for all of their telephone numbers.

Vodafone customers can enjoy an extra improvement with the new FRITZ!OS. It is now even easier to reconfigure the Vodafone account data entered during the first installation of the FRITZ!Box for a new DSL/VDSL line.

Additional improvements to the DSL software provide for improved stability and faster transmission over various connections.
The DSL diagnostics data have also been expanded for error analysis, so that future optimizations can be analyzed in even greater detail.
