Comes with all accessories, unused, direct from the manufacturer. Includes three ethernet cables and three power supplies for the router and two mesh wireless devices. This wireless access point is for use as a router only, not for bridging existing LAN's or repeating existing wireless networks. It has a very specific purpose to replace your existing Internet router and wireless access point and to give you two mesh wireless devices to provide strong wireless coverage throughout your home or office. Everything is tested to work plug-and-play. There is paper documentation on connecting a web browser to the router for basic configuration, but everything works out of the box after plugging in the power adapters and Internet ethernet cable into the main router.
