Newcomers to the lab

There was a lot going on at Fritz last week. The presentation of the Fritzbox DSL/Fiber 7-90 at the IFA in particular made headlines. The device not only ushers in a new era with tri-band Wi-Fi 7, but also comes in a fresh design. At the same time, the FritzBox 6690 Pro went on sale and there was also news from the laboratory in the form of fresh beta firmware for some of the Berlin company’s router models. Now there is a small addendum. On Friday, September 4th, additional FritzBoxes were provided with test updates and some were added to the current laboratory round. Accordingly, this means for these devices FritzOS 8.40 An extensive initial laboratory with numerous adjustments including some new functions is now available. The following routers are included:

After downloading, the update is installed via the router interface under “System” > “Update” and the “FritzOS file” tab. If you are installing a beta for the first time, you should also make sure that the latest stable version of FritzOS is running on the device. It also makes sense to create a backup copy of the device settings. If problems arise, this makes it easier to restore the FritzBoxes to their previous state in an emergency.
