Fritz!OS 8.20 update enhances Mesh WiFi, parental controls and more

Matthew Wilson July 30, 2025 General Tech

Fritz! is known throughout Europe for its easy-to-use routers, enabling customers to fully control their network and traffic. Today, Fritz!OS 8.20 is rolling out to all, packing optimised parental controls, a failsafe fallback system to keep your internet connection stable and more. 

AVM, the company behind Fritz!Box routers and the Fritz!OS, is now rolling out its latest software update, including over 40 improvements. The rollout begins today for the Fritz!Box 7590, the flagship WiFi 6 router. The update also makes improvements to Mesh WiFi setups and provides new energy saving options so you can take more direct control over your carbon footprint.

After the update, users can go into the online monitor and show utilisation for the past two weeks, filtering by devices or users eating up the most bandwidth. Using the Energy Efficient Ethernet feature, you can now reduce the energy consumption for your WAN and LAN sockets separately.

On the parental controls side, the Fritz!OS 8.20 update includes a new UI that clearly displays the access profiles and corresponding devices on one page, and tickets for online time are easier to find. The number of ‘online tickets' you can issue has also been increased from 10 to 12.

One of the most interesting features is the Fritz! Failsafe, a new fallback protection to help Fritz!Box users stay online without dropouts. FRITZ! Failsafe does this by using a substitute connection via a fallback device connected upstream from the FRITZ!Box as a reserve via a WAN, LAN or USB socket.

As for Mesh WiFi, setting up a mesh system is now simplified, so you no longer need to re-enter your password for each signal repeater you add to the system, and you can activate several repeaters at once without having to press the connection button on the Fritz!Box.

You can find full guides for setting up your Fritz!Box and managing your network for entertainment, cloud gaming, smart home devices and much more on the Fritz! website.

Dodgy tech retailer closes down after scamming RTX 5090 buyers for months

Earlier this year, we heard from a number of readers who had issues obtaining their paid-for product after pre-ordering RTX 5090 graphics cards from uwgamespecialist.nl, a tech retailer in the Netherlands. Following our initial report, the CEO of uwgamespecialist claimed that an internal investigation would be launched but by July of this year, we learned that the company was in fact still scamming customers. Now another couple of months later, the company appears to have shut down.
