# Enabling the Mesh Function

To check whether a FRITZ! product is enabled for Mesh, see the Mesh Overview of the FRITZ!Box (the Mesh Master) under "fritz.box -> Home Network -> Mesh".
Here the products in the Mesh are designated with a corresponding "Mesh active" symbol.

A FRITZ!WLAN Repeater or FRITZ!Powerline Adapter with FRITZ!OS 6.90 or higher installed can be enabled for Mesh in various ways:
- If the product has the ex works settings configured and is being connected with the FRITZ!Box for the first time, it will be automatically enabled for Mesh.
- If the product is already connected, but not enabled for Mesh, it is added to the Mesh by pressing a button on the product to be integrated and a button on the FRITZ!Box. On the FRITZ!Box, use the button that initiates WPS (depending on the model, press the "Connect" or "WPS" button briefly, or the "WLAN/WPS button for 6 seconds)

If you've received the second FRITZ!Box from your internet provider this feature may not work in some cases. Please configurate this FRITZ!Box as a mesh repeater by visit the FRITZ!Box GUI manually.
Instructions for configuring a FRITZ!Box connected via wireless LAN as a Mesh Repeater are presented at en.avm.de/mesh-faq
