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, 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 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 dierence. A solid metal door or aluminum studs may have a negative eect 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.
