Configuring a meshed WiFi network
Each VDOM on the FortiGate unit contains a predefined WiFi mesh interface named wl.mesh and a predefined SSID (which cannot be deleted) named fortinet.mesh.<vdom‑name>. You can create additional mesh SSIDs. Create the SSID with Traffic Mode set to Mesh Downlink.
You need to:
• Create custom AP profiles, if you are not using the automatic AP profile.
• Configure the mesh root AP, either a FortiWiFi unit’s Local Radio or a FortiAP unit.
• Configure mesh branch/leaf AP units.
• Authorize the mesh branch/leaf units when they connect to the WiFi Controller.
