Wireless Installation Considerations
The DIR-456 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 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 2.4GHz 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.
