Wireless Installation Considerations

The DAP-1665 wireless access point lets you access your network using a wireless connection from virtually anywhere within
the operating range of the device. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other
objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials
and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these
basic guidelines:
1. Keep the number of walls and ceilings between the D-Link access point and other network devices to a minimum. Each
wall or ceiling can reduce your adapter's range from 3-90 feet (1-30 meters.) Position your devices so that the number of
walls or ceilings is minimized.
2. Be aware of the direct line between network devices. At a 45-degree angle, a wall that is 1.5 feet thick (0.5 meters),
appears to be almost three feet (1 meter) thick. At a 2-degree angle, that wall appears to be over 42 feet (14 meters) thick!
For better reception, always position devices so that the signal will travel straight through a wall or ceiling (instead of at
an angle).
3. Building materials make a difference. A solid metal door or aluminum studs may have a negative effect on range. Try
to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways.
Materials and objects such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file cabinets, brick, and
concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems),
your wireless connection may also be affected. Make sure your 2.4 GHz phone base is as far away from your wireless devices
as possible. The base transmits a signal even if the phone is not in use.
