Update for Fritzbox and Co .: All functions and innovations

Table of Contents

AVM publishes an extensive software update for its devices once a year. FritzOS 7.1x is the current major firmware version and was released in September 2019. Since then, AVM has updated numerous Fritz boxes and Fritz devices with the software. But the next big update to FritzOS 7.2x is already announced. In advance, the company usually tests some of the functions it contains with minor updates from the Fritz laboratory. Here you can find out which devices AVM is currently offering an update for.


In the list we list both updates to the official FritzOS and the latest laboratory versions. Since AVM is only testing new functions in the Fritz laboratory, this software usually has a slightly higher version number than the official firmware.

The latest FritzOS updates at a glance

May 20: AVM officially delivers FritzOS 7.15

So far, the FritzOS 7.12 was the current and officially available firmware for the Fritz boxes. Now AVM is making a huge leap and is delivering the FritzOS 7.15 for the first time. The manufacturer promises a total of 50 improvements and new functions. The Fritzbox 6660 Cable is the first router to benefit from the update.

Since the device is a cable Fritzbox, it may take some time, depending on the provider, until the update has been adapted to its services and delivered to the customer. Those who operate the Fritzbox 6660 Cable without branding as an independent cable router can download the new firmware on the AVM website or directly via the router.

April 17: AVM updates Powerline adapter

The AVM device portfolio includes not only routers, but also DECT phones, WiFi repeaters, powerline adapters and various devices for the smart home. With the help of the Powerline adapter, users can distribute the Internet via the power grid in the house. This method is sometimes a more stable solution than WLAN – for example, for a constant internet supply for smart TVs. This is exactly where the current, official update comes in, which AVM is currently distributing for some of its Powerline adapters.

Depending on the model, the available updates have different version numbers. The Fritz! Powerline 1220E is updated to version and the Fritz! Powerline 1000E to The Fritz! Powerline 530E, however, is version and the Fritz! Powerline 510E is version

The update for the 500 models is clear. Here, AVM primarily introduces improvements in the area of ​​IP TV (especially Magenta TV from Telekom). However, the changelog for the updates of the 1220E and 1000E is more extensive. The manufacturer is advertising the following new products here:

  • IP TV improvements
  • Accelerated boot process
  • Data transmission improvements
  • New LED behavior in the event of a paring error: Powerline LED flashes for 4 seconds at 4 Hz

The innovations in the current FritzOS 7.19 laboratory

The latest laboratory firmware is version FritzOS 7.19-xxxxx. The ending differs depending on the update version and device. The FritzOS 7.19 has been available for a few months, but it has been adapted and expanded by AVM over the past few weeks, so that its functions are now very extensive.

The FritzOS 7.19 is now available as a laboratory update for a total of six routers. In addition to three cable routers that were supplied some time ago, there are now three devices for the (V) DSL connection:

  • Fritzbox 7530 (latest firmware on April 27)
  • Fritzbox 7590 (latest firmware on May 18)
  • Fritzbox 7490 (latest firmware on May 18)
  • Fritzbox 6591 Cable (latest firmware on May 20)
  • Fritzbox 6590 Cable (latest firmware on May 18)
  • Fritzbox 6490 Cable (latest firmware on May 18)

AVM also offers the new FritzOS for the following repeater models:

  • Fritz Repeater 3000 (latest firmware on April 21)
  • Fritz-Repeater 2400 (latest firmware on April 21)
  • Fritz-Repeater 1200 (latest firmware on April 21)
  • Fritz Repeater 1750E (latest firmware on April 21)

The innovations that AVM tests in the Fritz laboratory are extensive:


One of the most important innovations in FritzOS 7.19 is the integration of WPA3. The new WiFi encryption standard was adopted by the Wi-Fi Alliance in June 2018 and, as the successor to WPA2, brings even better authentication and encryption. The security at public hotspots can be increased and the configuration of WLAN devices should also be easier thanks to WPA3. It is important to mention that WPA3 should not replace the previous WPA2 standard, but rather should complement it. Both standards should be available in parallel for a longer period.

So that the Fritzbox automatically offers a WPA3 connection to corresponding WLAN devices, users must select the WPA mode “WPA2 + WPA3” in the router menu via “WLAN / Security”.

WiFi / mesh

Another innovation concerns the WLAN connections themselves. With an improved mesh steering, AVM wants to optimize the WLAN performance of connected devices. This works by checking the connections regularly to see if even better WiFi performance is possible. If this is the case, the Fritzbox automatically switches to the better WLAN connection as the mesh center.

Also interesting: AVM will soon no longer be providing updates for these Fritz boxes

Telephony and the Internet

FritzOS 7.19 brings support for encrypted telephony and a smart phone book for all FritzFon models. While entering the number, this already shows suitable contact suggestions. Online telephone books from Apple (iCloud), Telekom (Magenta Cloud) and CardDAV providers are now also supported. In the Internet area, AVM wants to increase the stability of VPN connections and has expanded parental controls.

There are some other small innovations in FritzOS 7.19, which include the smart home, but also USB connections and the general stability of the system. AVM summarizes these in detail on its laboratory website.

Fritz Laboratory: That has to be considered

If an update comes from the Fritz laboratory, different conditions apply compared to the official updates. With the laboratory firmware, AVM is testing new functions that will later become part of the large, official firmware update in late August or early September. Therefore, it has a beta character. The manufacturer also points out that there may be problems with the operation of the software.

Users can try out a Fritz laboratory if the current FritzOS is installed on their Fritzbox. Before installing the software, the data and settings on the router should be backed up for security reasons. Once this has been done, users can download the laboratory firmware in the Fritz laboratory from the AVM website and save it on their computer as a ZIP file. After unpacking the file, the following steps are necessary for installation:

  1. Call up the Fritzbox interface in the browser with http://fritz.box and enter the password for your Fritzbox if necessary
  2. At the bottom of the menu you will find the “View: Advanced” footer, which you must activate
  3. Now you will find the tab “FritzOS file” under “System / Update”
  4. In the input field, select the path to the previously downloaded and unpacked ZIP file and click on “Start update”

If laboratory firmware is already installed on the Fritzbox, a new update is automatically offered. Note that the update process can take a few minutes. The router’s info lamp flashes. When the update is complete, the Fritzbox restarts automatically. Data and settings are not lost, so that the router is ready for use again as usual.
