Positioning your wireless router

For the best wireless signal transmission between the wireless router and the network devices connected to it, ensure that you:

• Place the wireless router in a centralized area for a maximum wireless coverage for the network devices.
• Keep the device away from metal obstructions and away from direct sunlight.
• Keep the device away from 802.11g or 20MHz only Wi-Fi devices, 2.4GHz computer peripherals, Bluetooth devices, cordless phones, transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators, and other industrial equipment to prevent signal interference or loss.
• To ensure the best wireless signal, orient the three detachable antennas as shown in the drawing below.
• For optimum performance, adjust the internal cooling system. Refer to the user manual for details.
• Always update to the latest firmware. Visit the ASUS website at http://www.asus.com to get the latest firmware updates.
