1.3. Placing Your Wireless Range Extender
For best performance, refer to the following to place your wireless range extender:
The Best Way is Half-Way
Generally, the ideal location for the Range Extender is half-way between your
wireless router and Wi-Fi enabled devices. If that is not practical, placing the Range
Extender closer to your wireless router will ensure better performance.
Solid Green LED
Choose a location that lights up the green signal strength LED AAA
Less Interference = More Stability
Try to position your Range Extender away from electrical devices that are potential
sources of interference, such as ceiling fans, home security systems, microwaves, PCs,
refrigerators, the base of a cordless phone, or a 2.4 GHz cordless phone.
Less Obstacles = Better Performance
Try to choose a location that minimizes obstacles between the Range Extender and
your wireless router. Open corridors and other spacious locations will typically
provide better conditions for performance than a crowded room.
