Wireless Installation Considerations

The D-Link wireless device 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 device and other network devices to a minimum.
Each wall or ceiling can reduce your extender's range by up to 90 feet (more than 27 meters). Position your
devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. At a 45-degree angle, a wall that is 1.5 feet thick (0.5
meters), appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it can appear to be over 45 feet (almost
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 can 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.
