signal, for example, concrete structures or thick walls.
For your security and best Wi-Fi performance, please:
 Do NOT locate the modem router in a place where it will be exposed to moisture or
excessive heat.
 Keep away from the strong electromagnetic radiation and the device of electromagnetic
sensitive.
 Place the modem router in a location where it can be connected to the various devices as
well as to a power source.
 Make sure the cables and power cord are safely placed out of the way to avoid a tripping
hazard.
Generally, the modem router is placed on a horizontal surface, such as on a shelf or desktop.
