This is a set of four items: the tp-link Deco M4R router, which provides high-speed AC1200 Wi-Fi, the Deco M3W wireless LAN range extender, an AC adapter, and cables. The Deco M4R router has some discoloration on the surface due to sun exposure (see photo 2), but both the router and the range extender function properly. (The top of the router lights up yellow in photo 7). The box and instruction manual are not included, but you should be able to find the information on the website. When using the devices, please press the reset button on the bottom before connecting.
