Near the center of the area where your computers, smart phones and other devices operate, and
preferably within line of sight to your wireless devices.
In an elevated location such as a high shelf, keeping the number of walls and ceilings between this
device and your other devices such as computers and smart phones to a minimum.
Away from electrical devices that are potential sources of interference, such as ceiling fans, home
security systems, microwaves or PCs.
Away from any large metal surfaces, such as a solid metal door or aluminum studs.
Away from other materials such as glass, insulated walls, fish tanks, mirrors, brick and concrete
that can also affect your wireless signal.
