Fritz-Labor: That has to be considered

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 unzipping 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 that the router is ready for use again as usual.
