Typically, AVM initially provides lab versions for the most popular models to leverage feedback to improve future versions for additional Fritz boxes and Fritz accessories. For which Fritzbox there is a current lab version, you can see on the Fritz OS website, because the lab version should not be installed on Fritzbox, which is used for everyday Internet and WLAN access. Beta firmware can be unstable and cause Fritzbox to crash.
The more advanced the development of the laboratory, the lower the risk of router failure. Problems can still occur with special applications such as IPTV or proper integration of smart home devices. If you are ready for it, you can install the laboratory version and try it without risk and in case of problems quickly import the official Fritz OS at that time.
AVM has updated the look of the Fritzbox offering with Fritz OS 7.50. The colors look more modern and the menus are clearer. The new Fritzbox interface should also be easier to use via a smartphone.
The user interface of the new Fritz OS looks clearer and clearer: the router menu is also easier to control with a smartphone.
The menu categories in the left column were given more recognizable icons. In addition, an obvious new point appears here with the “Info Center”: It refers to the contents of the Fritzbox settings, which could previously be accessed via the “Contents” item at the bottom left.
In the current lab, there is no longer a switch between the “Standard” view, in which some setting options are not displayed, and the “Advanced” view. Instead, AVM now uses collapsible submenus that hide additional settings for better overview. Quick access to “MyFritz!” And “FRITZ! -NAS” is now easier to recognize thanks to the redesigned buttons at the top right.
The modified menu structure is particularly clear for “WLAN -› Radio network “: Here you can immediately see the settings of the network SSID and WiFi password, including the QR code for a quick connection to the radio network. This information is currently only displayed at the bottom of this menu page. WLAN settings are also clearer thanks to other drop-down menus, such as “Additional information about the WLAN radio network”: only after clicking on it, information about the MAC addresses of the Fritzbox radio modules and the option to hide the SSID are displayed.
Important settings can be reached faster in Fritz-OS 7.50: For example, the SSID and network password as well as the QR code for logging in are at the top of the WLAN menu.
Radio channel settings (“Edit radio channel settings”) are also easier to use because the options for different frequency bands are now arranged side by side, not below each other.
In order to confirm or reject the changed settings, Fritzbox now displays the corresponding buttons at the bottom of the menu, which you use instead of the previously fixed areas at the bottom right, or confirmation windows, which are located centrally above the menu interface.
Fritz OS 7.50 offers a new fun feature in conjunction with Fritzfon: AVM’s DECT device uses voice to tell who is calling or where the call is coming from. The prerequisite for this is an active Myfritz account for the Fritzbox in question and the current firmware on Fritzfon. You can do the latter either by displaying the home network in the Fritzbox menu under “Home network -› Mesh “or directly on the Fritzbox under” Settings – ›Software version -› Check “.
For voice announcements, Fritzbox evaluates the entries in the directory: Fritzfon then no longer announces the incoming call by ringing, but, for example, by announcing “Call from boss”. If the caller is not stored in the Fritzbox phonebook, the Fritzfon announces the place from which the call is made – as is currently the case on the phone display.
You can also have appointment reminders or the Fritz-Fon alarm signal by voice instead of sound. Fritzbox also uses a text-to-speech engine to indicate the name or location of the caller when listening to messages on the answering machine.
The Fritzphone can read the caller’s name if there is a matching entry in the Fritzbox directory. To do this, select “Voice Ringtone”.
Set up a voice ringtone in the Fritzbox in the “Telephony -› Telephone devices “section. Click on the edit symbol on the Fritzphone and go to the “Ringtones” menu. If the handset answers a specific phone number, select Voice Ring from the drop-down menu for that number. Otherwise, you will find this setting in the “other external call” line.
You will also find the “Caller ID / Voice Ring Settings” menu on the page: Here you can activate a male or female voice as a voice output or also set a ringtone to sound before the voice ring.
If you want to be reminded of a meeting or a Fritzphone voice alarm time, change the settings directly in the handset menu. For example, for the alarm you set in the “Convenient services” section, select “Language (female)” or “Speech (male)” in the “Alarm tone” section. Under “Text” you can also enter special text that the voice output will say when you wake up.
A novelty for Fritzfon is the meeting calendar, which you will find under “Comfort Services”. There you can create reminders for specific days and times, which can also be repeated. As with the alarm clock, Fritzfon will alert you to the appointment with the bells.
Another new feature makes it easier to deal with annoying advertising calls in Fritz OS 7.50: All callers who are not in the Fritzbox phonebook can now be automatically rejected or diverted to an answering machine or other number. To set the appropriate call barring, go to “Telephony -› Call handling – ›Call barring” in the Fritzbox menu. In the Incoming Call Blocking section, click Add Range. Select “Not in Phonebook” from the drop-down menu. Follow these steps to divert calls.
