Wireless Installation Considerations
The DCS-5230 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 ofce. 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 sh tanks, mirrors, le 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, uorescent
lights, and home security systems may dramatically degrade wireless connectivity.
