Wireless Installation Considerations

The DIR-685 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. Ranges vary depending on the types
of materials and background RF (radio frequency) noise in your home or office. The key to maximizing the 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 to 90 feet (1 to 30 meters.) Position your
devices so that the number of walls and/or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (0.5 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. Try to position access points, wireless routers, and computers so that the signal passes through open
doorways and drywall. Materials such as glass, metal, brick, insulation, concrete and water can affect
wireless performance. Large objects such as fish tanks, mirrors, file cabinets, metal doors and aluminum
studs may also have a negative effect on range.
4. Keep your product at least 3 to 6 feet (1-2 meters) away from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz cordless phones, make sure that the 2.4GHz phone base is as far away from
your wireless device as possible. The base transmits a signal even if the phone in not in use. In some
cases, cordless phones, X-10 wireless devices, and electronic equipment such as ceiling fans, fluorescent
lights, and home security systems may dramatically degrade wireless connectivity.
