FRITZ! Lab for Mesh WiFi

Mesh WiFi with FRITZ!

The FRITZ!Box serves as the home network hub, and passes the Internet connection of DSL, cable, LTE or fiber optic lines on to your home and small office via high-performance WiFi. Increasingly fast Internet connections, more web-enabled devices, video and gaming applications, and, especially, spatial extensions can lead to increased demand for WiFi performance and coverage. Due to their modular design and compact form (as outlet adapters), FRITZ!WLAN Repeaters and FRITZ!Powerline adapters with WiFi offer an appropriate and optimized expansion of the wireless network.

The smooth interaction of these products and devices is commonly associated with the term "mesh", and yields high performance, robustness and uninterrupted connections for the wireless LAN in the home network and in every space. "Mesh" means that the FRITZ! products build a homogenous network, are always connected and coordinated in an optimal manner, and provide for more convenience and performance. All FRITZ! products exchange information in the mesh network, synchronizing settings, optimizing the performance of connected terminal devices, and they do so independently, smoothly and without any user input.

For this to work, a number of central features are required - and these have been part of the FRITZ!OS operating systems for years already. In particular, these include:

Installation on the FRITZ!Box

You're not using the current FRITZ!OS in your FRITZ!Box yet? Then first update FRITZ!OS to the latest release version. Here we tell you how this works.

Once your FRITZ!Box has the latest FRITZ!OS installed you can start installation of the lab version.

  1. Read and confirm the information displayed.
  2. Click "Download" and save the file on your computer.
  3. Unpack the lab file (*.zip)
  4. Use the FRITZ!Box user interface to install the update and then select "View: Advanced" in the footer.
  5. Select the "System / Update" menu.
  6. Select the "FRITZ!OS file" tab. Save the settings of your FRITZ!Box.
  7. Then enter the name of the lab version with its complete path in the input field (e.g. C:\Documents and Settings\<user>\Desktop\FRITZ!Box-Lab-xxxx.image).
  8. Click "Start Update".
  9. Follow the instructions displayed on the screen.

During the update process the "Info" LED on your FRITZ!Box will flash. The LED goes out once the update is complete. Please be patient, as this process may take several minutes. As soon as the update has been completed, the FRITZ!Box restarts and is then ready for operation.

Note when using multiple FRITZ!Boxes: only one FRITZ!Box can and must play the role of the "Mesh Master". In the default setting, this is the Box with the direct connection to the Internet. You can adjust the role of a FRITZ!Box within the mesh network over the support page (

Installation on FRITZ!WLAN Repeater 1750E, 1160, 450E and 310 and FRITZ!Powerline 1240E, 546E and 540E

  1. First update your FRITZ!Box to the lab version (see "Testing the Lab Version")
  2. After updating the FRITZ!Box, open the user interface at and select "Home Network" -> "Home Network Overview".
  3. Here you see the new graphical Home Network Overview, which shows all of the connections in the home network. If you have the FRITZ!Repeater 1750E, 1160, 450E and 310 or FRITZ!Powerline 1240E, 546E and 540 in your network, an update is displayed for these devices. Trigger the update by clicking on "Update available".
  4. After the update the products should be marked with an additional mesh symbol. This indicates that they are part of the mesh network and will benefit from the expanded features. If one of your FRITZ!WLAN Repeater 1750E, 1160, 450E and 310 or FRITZ!Powerline 1240E, 546E and 540E devices is not marked with the mesh symbol, please enable the device for the expanded mesh function manually (see the "Changed Button Behavior in FRITZ!OS 6.88 or Later" in the infolab.txt attached).

Activating the mesh function

After updating your repeaters and powerline with WiFi support over the Home Network Overview of the FRITZ!Box, mesh should automatically be activated for your product – as indicated by the mesh symbol at the corresponding product display in the connection overview.

If this is not the case, then you can activate the device for mesh later. To do so proceed as follows:

  1. Prepare the FRITZ!Box to integrate a new device into the mesh network:
  2. FRITZ!Box 7490: press the WLAN/WPS button (6 seconds)
  3. FRITZ!Box 7590: press the "Connect/WPS" button briefly

Trigger the mesh connection of FRITZ!WLAN Repeater or FRITZ!Powerline with WiFi:

Briefly press the WPS or Powerline Security button.


This FRITZ! Lab version is a beta. We tested the software in standard environments before making it available to the public, but it may still result in malfunctions. AVM will not be liable for any damages that arise from the use of the lab version. Of course you can reinstall a regular version of FRITZ!OS for the FRITZ!Box using the Windows recover.exe program included in this lab package at any time.

Please also note the information about the use of lab versions in the labinfo.txt. It is contained in the lab file (*.zip).

Attention: The official FRITZ!OS can only be reinstalled with the Windows Recover program included in this lab version.
