Wireless Installation Considerations
Section 2 - Installation
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within
the operating range of your wireless network. 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 router 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.
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.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
range. Try to position access points, wireless routers, and computers so that the signal passes through
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
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.
generate RF noise.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
home security systems), your wireless connection may degrade dramatically or drop completely. Make
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.
