Wireless Installation Considerations
The D-Link wireless router 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 -90 feet (1-0 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  feet (1 meter) thick. At a -degree angle it looks over 4 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 -6 feet or 1- meters) from electrical devices or appliances that generate RF
noise.
5. If you are using .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 .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.
