Wireless Basics (continued)

Installation Considerations

The DWL-G122 lets you access your network using a wireless connection from virtually anywhere within its operating range. 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:

1Keep the number of walls and ceilings between the DWL-G122 and other network devices to a minimum - each wall or ceiling can reduce your DWL-G122’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.

2Be 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.

3Building materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials.

4Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
