Wireless Installation Considerations - D-Link DWR-921 User Manual

The DWR-921 can be accessed using a wireless connection from anywhere within the operating range of your wireless network. Keep in mind
that the quantity, thickness, and location of walls, ceilings, or other objects that the wireless signals must pass through may limit the range of
the wireless signal. 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. Minimize the number of walls and ceilings between the router and other network devices. Each wall or ceiling can reduce your
adapter's range from 3 to 90 feet (1 to 30 meters).
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 can appear 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 or drywall. Materials
such as glass, metal, brick, insulation, concrete, and water can affect wireless performance. Large objects such as fish tanks, mirrors,
filing cabinets, metal doors, and aluminium studs may also have a negative effect on range.
4. If you are using 2.4 GHz cordless phones, make sure that the phone base is as far away from your wireless device as possible. The base
transmits a signal even if the phone is 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.
