September 17th: Fritz! OS update for the 7490 and 7430

A good week ago, AVM provided a laboratory for the Fritzbox 7490. Now another update follows – the former flagship router receives Fritz! OS 7.21. The Fritzbox 7430 was also supplied with the new firmware by AVM. Almost all current routers from AVM now run with the new Fritz! OS.

The update is accompanied by numerous innovations. From Fritz! OS 7.20 onwards, AVM implements, among other things, the WPA3 encryption standard, which brings significant improvements in the authentication and security of wireless networks. A public WLAN hotspot can now also be set up on the WLAN guest access, where the data is securely encrypted and transmitted thanks to “Enhanced Open / Opportunistic Wireless Encryption” (OWE). “Performance Mesh Steering” is also one of the innovations of the update, the features of which we will list in more detail below in this message.

September 9: Laboratory updates for various Fritz boxes

The current updates that AVM is currently rolling out are new software from the Fritz Laboratory. The Berlin router manufacturer supplies some of its most popular Fritz boxes. Among other things, the beta firmware should provide better telephony and more stable WLAN connections. It also prepares the routers for the major firmware update if they are not yet supplied with Fritz! OS 7.20. The following updates are currently available:

Fritzbox 6660 Cable

The Fritzbox 6660 Cable has already received the update to Fritz! OS 7.21. Now AVM is immediately delivering an up-to-date laboratory. It bears the version number FRITZ! OS 7.21-81803 and mainly contains three new features. Among other things, AVM has improved the registration at the touch of a button (Connect / WPS), which should now be more reliable. The manufacturer has also corrected minor errors that could appear on the information sheet with access data for the WLAN guest access. Last but not least, the Fritz laboratory also improves the stability of the entire system.

Fritzbox 6890 LTE

The changelog of the current laboratory 07.19-81754 for the Fritzbox 6890 LTE is much more extensive. There were no updates for the cellular router for a few weeks, so AVM was able to implement a lot of innovations. At the same time he prepares the Fritzbox for the Fritz! OS 7.20. This step was already taken with the other two routers, although the laboratory updates were similarly extensive at the time. AVM specifies the following changelog for the Fritzbox 6890 LTE:

Cellular network:
Fixed – Occasionally incorrect display of the cellular network provider on the overview
page. Fixed – Instability with active debug analysis

September 4th: Fritzbox 6591 Cable gets Fritz! OS 7.21

After the cable Fritzbox 6590, AVM has now also provided the newer model Fritzbox 6591 Cable with the update to Fritz! OS 7.21. The Berlin router manufacturer is not only increasing security with this, it also brings more convenience for users in many areas. After the August updates, the current AVM routers for Internet via cable with the current firmware are now running.

20-31. August: Cable Fritz boxes get Fritz! OS 7.21

AVM continues and also provides the Fritzbox 6660 Cable and the Fritzbox 6490 Cable with an update. The 6660 Cable even gets a more recent firmware version – the Fritz! OS 7.21. There are no major changes between versions 7.20 and 7.21. AVM has mainly worked on the stability and integrated some bug fixes.

Owners of a cable Fritzbox purchased over the counter can update their router immediately. However, if the device comes from the cable provider, the update must first be adapted and approved, which can take some time.

ugust 17th: More Fritzbox and Fritz! Repeaters receive Fritz! OS 7.20

Other AVM products will receive the major firmware update sooner than expected. In this cycle, AVM not only updates the Fritzbox 6590 Cable router. The Fritz! Repeaters 1750E and 3000 also receive the new firmware. All three devices receive the update automatically.

July 22nd: AVM supplies further devices with the Fritz! OS 7.20

When Fritz! OS 7.20 started, the firmware was initially only available for the Fritzbox 7590. In the meantime, AVM has also expanded the update to other devices. After the Fritzbox 7530 received the preparatory laboratory as a release candidate in mid-July, the Fritz! OS 7.20 is now officially available for download. At the same time as the 7530, the Fritzbox 7520 and the WLAN repeater 2400 received the update.

The innovations in the current FritzOS 7.20

With the Fritz! OS 7.20, AVM claims to deliver over 100 new functions and optimizations for its Fritz devices. These should not only increase the performance of the Fritz boxes, but also improve WLAN connections from mobile devices, enable faster and more stable connections via VPN networks and ensure more security in the home network. Overall, AVM is introducing innovations in all core areas such as the Internet, telephony, smart home and home network.

Fritz Labor: That is important to note

If an update comes from the Fritz Laboratory, different conditions apply compared to the official updates. Because with the laboratory firmware, AVM is testing new functions that will later become part of the large, official firmware update at the end of August or beginning of September. It is therefore beta. The manufacturer also points out that problems can arise when operating 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 to be on the safe side. Once this is done, users can download the laboratory firmware in the Fritz Laboratory from the AVM website and save it as a ZIP file on their computer. 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 footer “View: Advanced”, which you have to activate
  3. You will now find the “FritzOS file” tab under “System / Update”
  4. In the input field, select the path to the previously downloaded and unzipped ZIP file and click on “Start update”

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