3 D-Link DWL-3140AP Hardware Installation Guide
Installation Considerations
D-Link wireless devices allow you access your network using a wireless connection
from virtually anywhere within the operating range of your wireless network. 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 number of walls and ceilings between the D-Link access point
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.
2.
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.
3. 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.
4.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.
5.
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 is not in use.
