What is the best way to position my Netgear Nighthawk router for WiFi coverage?

Place the router near the center of the area where your devices operate and within line of sight to WiFi devices. Position it in an elevated location to minimize walls and ceilings between the router and devices. Keep it away from electrical devices like microwaves, cordless phones, and base stations, as well as large metal surfaces, fish tanks, mirrors, and concrete walls. (Page 16)
