Section 2 - Installation
When using the DIR-457/DIR-457U in Wi-Fi router mode, placement of the device is very important. Do not place the
device in an enclosed area such as a closet, cabinet, or in the attic or garage. Please install the device considering
the following points:
The D-Link DIR-457/DIR-457U in Wi-Fi router mode 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 router 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.
