Fritz Lab: What you need to know
If an update comes from the Fritz Lab, different conditions apply compared to the official updates. This is because AVM uses the lab firmware to test new functions that will later become part of the large, official firmware update at the end of August or beginning of September. It therefore has beta character. The manufacturer also points out that there may be problems when operating the software.
Users can try out a Fritz Lab if the current FritzOS is installed on their Fritzbox. Before installing the software, however, the data and settings on the router should be backed up to be on the safe side. Once this has been done, users can download the Fritz Lab firmware from AVM’s website and save it on their computer as a ZIP file. After unpacking the file, the following steps are then necessary for installation:
- Call up the Fritzbox interface in the browser with http://fritz.box and enter the password for your Fritzbox if necessary.
- At the bottom of the menu you will find the footer “View: Advanced”, which you have to activate
- Now you will find the tab “FritzOS file” under “System / Update”.
- Select the path to the previously downloaded and unzipped ZIP file in the input field and click on “Start update”.
If a lab firmware is already installed on the Fritzbox, a new update will be offered automatically. Note that the update process may take a few minutes. During this time, the router’s info lamp flashes. Once the update is complete, the Fritzbox restarts automatically. Data and settings are not lost, so the router is ready for use again as usual.
