DNS-G120 User's Manual Wireless Basics Wireless Installation Considerations The DNS-G120 lets you access your stored data and media files 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 DNS-G120 and other network devices to a minimum - each wall or ceiling can reduce your DNS-G120'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. A wall that is 1.5 feet thick (.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 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 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your wireless connection may degrade dramatically or drop completely. Make 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. D-Link Systems, Inc. 10

Wireless Installation Considerations
The DNS-G120 lets you access your stored data and media files 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:
Keep your product away (at least 3-6 feet or 1-2 meters) from
electrical
devices or appliances that generate RF noise.
4
Keep the number of walls and ceilings between the DNS-G120 and
other network devices
to a minimum - each wall or ceiling can reduce
your DNS-G120’s range from 3-90 feet (1-30 meters.) Position your
devices so that the number of walls or ceilings is minimized.
1
Be aware of the direct line between network devices. A wall that
is 1.5 feet thick (.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.
2
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.
3
If you are using 2.4GHz cordless phones or X-10 (wireless products
such as ceiling fans, lights, and home security systems), your
wireless connection may degrade dramatically or drop completely.
Make 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.
