Current Fritzbox updates at a glance
Lab for Fritz!OS 7.39 with new features for various Fritzboxes
AVM is currently working on the update to Fritz!OS 7.50, which promises numerous optimizations and innovations. Until then, smaller updates for various Fritzboxes are running through the Fritz Lab. New software is currently available for several router models.
The DSL routers Fritzbox 7590 AX, 7590 and 7530 as well as the cable routers Fritzbox 6591 Cable and 6660 Cable get the update to Fritz!OS 7.39. The Fritzbox 6850 LTE is also updated. Fritz!OS 7.39 brings numerous new functions with it. These include new routines and templates for Smart Home, a caller greeting for calls, alarm clocks and appointments, an appointment calendar for the Fritz phones, support for exFAT-formatted storage media and more. AVM has published a full list here.
The changelog of the new lab firmware for the said Fritzboxes is identical for all models and quite extensive. In addition to the new features, AVM also delivers adjustments in the areas of Internet, WLAN and home network with the Fritz Lab.
- Improvement No publication of the IPv4 address to MyFritz!Net on dual-stack connections with carrier-grade NAT; resolution of the MyFritz! address is always to the IPv6 address here.
- Improvement New setup wizard simplifies the creation of WireGuard connections
- Improvement New message under “System / Events” when a new session key has been negotiated (connections according to WPA3/SAE standard)
- Fixed Setting of WLAN transmit power also for public WLAN guest access possible again
- Fixed Page “WLAN / Radio Channel” was not completely displayed with Safari under MacOS/iOS/iPadOS
- Improvement Detail pages of network devices have been revised
- Fixed Changes in the detail pages of a network device erroneously activated the lock of the device
- Fixed Image display for RSS feeds reliable again
- Improved Volume of speech increased during voice ringing
- Improvement Google calendar setting can be updated via a button
- Improvement Routines can be activated and deactivated via templates
- Fixed Incorrectly sent change notice for additional confirmation option has been removed
- Improvement When calling the link to the lab feedback, the Fritz!OS version is transmitted as well
An interesting feature here is the support of WireGuard for the simple establishment of VPN connections. The VPN solution is faster, simpler and leaner than IPSec and, unlike IPSec and OpenVPN, relies on a reduced number of
(state-of-the-art) cryptographic methods. As a result, WireGuard is also generally easier to configure.
Fritz!OS 7.31 for Fritzbox 7583 VDSL, 7583 and 7530 AX
A good month after the Fritzbox 7590 AX, the Fritzbox 7530 AX also has the update to Fritz!OS 7.31. A short time later, AVM also provides the update for the Fritzbox 7583 with and without VDSL. The jump to the new version number is primarily a maintenance update that does not bring any major innovations. With the update, AVM primarily delivers adjustments to support provider-specific services and improves the general stability of the system. However, the router manufacturer does not reveal exactly which adjustments are involved.
Fritzbox 7590 AX gets Fritz!OS 7.31
AVM has provided an update for the Wifi-6 version of the Fritzbox 7590. The Fritz!OS 7.31 should primarily ensure smoother Internet connections. For this, the stability has been increased for Supervectoring (35b) and Vectoring (17a) as well as for ADSL2+. In addition, AVM has improved data rates to certain ADSL2+ peers and interoperability.
Update for mobile Fritzboxes
An update is also available for the Fritzbox 6840 LTE. The LTE router receives Fritz!OS 6.87, where the trusted root certification authorities have been updated and security in WLAN communication has been increased. AVM has also made the following adjustments:
- Fixed Vulnerabilities in the handling of incoming fragmented packets as well as aggregated MPDUs (A-MPDU) fixed (“Fragattack”).
- Improvement Certificates updated and stability increased
- Improvement Automatic software update for Fritz-Fon M2
The manufacturer again upgrades the software of the Fritzbox 6850 5G to Fritz!OS 7.30. There are no extensive new features here. Instead, a bug in the support of certain SIM cards is fixed. It could happen that cards from the provider Sunrise/Switzerland were not recognized.
The innovations in the current FritzOS
With the latest Fritz!OS, AVM says it is delivering numerous new features and optimizations for its Fritz devices. These should not only increase the performance of the Fritzboxes, but also improve WLAN connections from mobile devices, enable faster and more stable connections via VPN networks and provide more security in the home network. Overall, AVM is introducing innovations in all core areas such as Internet, telephony, smart home and home network.

Fritz Lab: What you need to know
If an update comes from the Fritz Lab, different conditions apply compared to the official updates. This is because AVM uses the lab firmware to test new functions that will later become part of the large, official firmware update at the end of August or beginning of September. It therefore has beta character. The manufacturer also points out that there may be problems when operating the software.
Users can try out a Fritz Lab if the current FritzOS is installed on their Fritzbox. Before installing the software, however, the data and settings on the router should be backed up to be on the safe side. Once this has been done, users can download the Fritz Lab firmware from AVM’s website and save it on their computer as a ZIP file. After unpacking the file, the following steps are then necessary for installation:
- Call up the Fritzbox interface in the browser with http://fritz.box and enter the password for your Fritzbox, if necessary.
- At the bottom of the menu you will find the footer “View: Advanced”, which you must activate
- Now you can find the tab “FritzOS file” under “System / Update”.
- In the input field, select the path to the previously downloaded and unzipped ZIP file and click on “Start Update”
If a lab firmware is already installed on the Fritzbox, a new update will be offered automatically. Note that the update process may take a few minutes. During this time, the router’s info lamp flashes. Once the update is complete, the Fritzbox restarts automatically. Data and settings are not lost, so the router is ready for use again as usual.
