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 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 in not in use.
