Installation Considerations

The D-Link Air DWL-120 lets you access your network, using a wireless
connection, from virtually anywhere. Keep in mind, however, that the number,
thickness and location of walls, ceilings, or other objects that the wireless signals
must pass through, may limit the range. Typical ranges vary depending on the
types of materials and background RF (radio frequency) noise in your home
or business. The key to maximizing wireless range is to follow these basic
guidelines:
1. Keep the antenna of the DWL-120 in an upright position.
2. Keep the number of walls and ceilings between the DWL-120 and
other network devices to a minimum - each wall or ceiling can reduce
your D-Link Air Wireless product's range from 3-90 feet (1-30 meters.)
Position your receiving devices so that the number of walls or ceilings is
minimized.
3. Be aware of the direct line between network devices. A wall that is 1.5 feet
thick (.5 meters), at a 45-degree angle appears to be almost 3
feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters)
thick! Try to make sure that devices are positioned so that the signal will
travel straight through a wall or ceiling for better reception.
4. Building Materials make a difference - a solid metal door or aluminum
studs may have a negative effect on range. Try to position wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.
