Wireless Installation Considerations
The D-Link wireless adapter lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind 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 adapter 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 dierence. A solid metal door or aluminum studs may have a negative eect 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 (sh tanks),
mirrors, le 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 in not
in use.
