Onboard and manage the system in the TP-Link Deco mobile app with a TP-Link ID. connect one unit to the modem or upstream gateway, wait for its setup LED state and complete the guided flow in the Deco app before adding satellites. Each unit can lead a Deco network in router mode or operate as an access point/satellite; any auto-sensing port may become WAN on the main unit. TP-Link states that Deco models can share one mesh; features depend on the main Deco, while radio, port and hardware-version limits remain model-specific. TP-Link permits mixed Deco networks, but it recommends using the most capable unit as the main Deco and placing nodes so that wireless or Ethernet backhaul matches the available hardware.
