Wireless Installation Considerations
The DWR-116 can be accessed using a wireless connection from virtually anywhere within the operating range of your wireless
network. Keep in mind, however, that the quantity, 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. 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 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
or 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 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.
