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. However, 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 usage area. You can optimize wireless range and signal strength
by following these basic guidelines:
Keep the number of walls and ceilings between the router and other network devices to a minimum - each
wall or ceiling can reduce your network's range by up to 30 meters (98 feet). Position your devices so that
the number of walls or ceilings in the signal's path is minimized.
Be aware of the direct line between network devices. A wall that is 0.5 meters thick (1.5 feet) appears to
be almost 1 meter (3 feet) thick at a 45-degree angle. At a 2-degree angle it appears 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.
Building materials make a difference. A solid metal door or aluminum studs may have a detrimental 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.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate
RF noise.
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.
