Wireless Installation Considerations

The DWR-512 can be accessed using a wireless connection from virtually 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 D-Link 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 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. If you are using 2.4 GHz cordless phones, make sure that the 2.4 GHz 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.
