FritzOS 8.50: Beta Versions Released for Fritzbox Models

Fritz released new beta versions of FritzOS 8.50 for seven models of its Fritzbox routers on September 28, 2026. These beta versions are intended for users who wish to test the software prior to its official release. The models receiving the new software include DSL, fiber, and cable routers. The current beta version is available for the following Fritzbox models: Fritzbox 7630, Fritzbox 5690 Pro, Fritzbox 5690 XGS, Fritzbox 5590 Fiber, Fritzbox 6690 Cable, Fritzbox 6670 Cable, and Fritzbox 6660 Cable.

For six of these models, the changes primarily focus on general improvements to system stability. The beta versions for most models do not include new features that would be immediately visible to users. Instead, the adjustments aim to enhance the reliability of the routers. This is particularly relevant for users who have already installed a previous beta version and are hoping for more stable performance. However, the Fritzbox 7630 receives several specific bug fixes.

These include improved registration of phone numbers via a mobile connection with the provider Easybell. Additionally, the assistant for transferring settings to a new Fritzbox has been revised to facilitate easier migration for users. There is also an adjustment in the display of information regarding the new FritzOS version after an update. Another fixed issue concerns the interaction with Amazon devices in the home network. Under certain circumstances, these devices could generate a high number of mDNS requests, unnecessarily burdening the home network.

Another important point is the correction of the PPPoE passthrough. This feature allows another router to operate behind the Fritzbox, managing the internet connection itself. With the new beta version, this function is now expected to work correctly again, particularly on DSL connections. The beta software is currently not available to all users. Those already using a beta version can access the new version through the Fritzbox interface under System > Update.

For users who wish to install a beta version for the first time, the appropriate firmware file is available on the Fritz beta page. The release of the final version of FritzOS 8.50 is highly anticipated by many users, as the short change logs suggest that development may be largely complete. However, an official announcement regarding the release is still pending. The beta versions are an important step for users interested in improving the software. Feedback from the community could be crucial for final adjustments before the software is released to all users.

However, the exact timeframe for the final release remains unclear. The beta versions are part of Fritz's ongoing commitment to enhancing the user experience and ensuring the stability of their products. Users can look forward to further updates and improvements in the future. The current beta version of FritzOS 8.50 for the Fritzbox 7630 addresses issues with mobile registration and mDNS requests, optimizing the performance of the home network.
