Installation Considerations
The DWL-G520M lets you access your network using a wireless connection from
virtually anywhere within its operating range. 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:
Installation Considerations



Keep your product away (at least 3-6 feet or 1-2 meters) from
electrical devices or appliances that generate RF noise.
Keep the number of walls and ceilings between the DWL-G520M
and other network devices to a minimum - each wall or ceiling can
reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
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! Position devices so that the signal will travel
straight through a wall or ceiling (instead of at an angle) for better
reception.
Building Materials make a difference. A solid metal door or aluminum
studs may have a negative effect on range. Try to position access
points, wireless routers, and computers so that the signal passes
through drywall or open doorways. Materials and objects such as
glass, steel, metal, walls with insulation, water (fish tanks), mirrors,
file cabinets, brick, and concrete will degrade your wireless signal.
If you are using 2.4GHz cordless phones or X-10 (wireless products
such as ceiling fans, lights, and home security systems), your
wireless connection may degrade dramatically or drop completely.
Make sure your 2.4GHz phone base is as far away from your
wireless devices as possible. The base transmits a signal even if
the phone in not in use.
