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 the number and thickness of walls and ceilings, as well as the location of 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 by 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings

is minimized.

2. Strive for a direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle will appear to be

almost 3 feet (1 meter) thick. At a two-degree angle it appears to be over 42 feet (14 meters) thick! Position your devices so that

the signal will travel straight through a wall or ceiling, instead of at an angle, for the best reception.

3. Be aware of the type of building materials separating your devices. 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 three to six feet) 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 when the phone in not in use.
