1.4 Positioning your router
For optimal wireless transmission between the wireless router and
connected wireless devices, ensure that you:
• Place the wireless router in a centralized area for a maximum
wireless coverage for the network devices.
• Keep the wireless router within the view of sight of a window
or clearance, and away from metal or solid obstructions and
direct sunlight.
• Keep the wireless router away from conventional radio
emission devices operating within the 2.4GHz spectrum.
Devices such as Bluetooth, cordless phone, transformer, heavy
duty motors, fluorescent lights, microwave oven, refrigerators,
and other industrial equipments may interfere with the
smooth transmission of 2.4GHz WiFi.
• Always update to the latest firmware. Visit the ASUS website
at http://www.asus.com to get the latest firmware updates.
• Orient the antennas as shown in the drawing below.
