1.4 Positioning your 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.
• To prevent signal interference or loss, 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 ensure the best wireless signal, orient the three detachable
antennas as shown in the drawing below.
