The D-Link Air Premier
®
DWL-7700AP
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:
Installation Considerations
1
Keep the number of walls and ceilings between the
DWL-7700AP
and other network
devices to a minimum - each wall or ceiling can reduce your DWL-7700AP ’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 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.
4
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate RF noise.
