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 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 1 to 30 meters (3 to 90 feet). 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 0.5 meters (1.5 feet) thick, at a 45-degree angle appears to be
almost 1 meter (3 feet) thick. At a 2-degree angle it looks over 14 meters (42 feet) 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 1 to 2 meters (3 to 6 feet) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz 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 2.4 GHz 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.
