WIRELESS BASICS
1. Keep the number of walls and ceilings to a minimum -
Each wall or ceiling can rob your D-Link Air Wireless
product from 1-30M of range. Position your Access
Points, Residential Gateways, and computers so that
the number of walls or ceilings is minimized.
2. Be aware of the direct line between Access Points,
Residential Gateways, and Computers -
A wall that is .5 meters thick, at a 45 degree angle
appears to be almost 1 meter thick. At a 2 degree
angle it looks over 14 meters thick! Try to make sure
that the AP and Adapters are positioned so that the
signal will travel straight through a wall or ceiling for
better reception.
3. Building Materials make a difference -
A solid metal door or aluminum studs may have a neg-
ative effect on range. Again, try to position Access
Points, Residential Gateways, and Computers so that
the signal passes through drywall or open doorways
and not other materials.
4. Make sure that the antenna is positioned for best reception
by using the software signal strength tools
included with your product.
5. Keep your product away (at least 1-2 meters) from electrical devices
that generate RF noise, like microwaves, Monitors,
electric motors, etc.
For the average American 4-bedroom home, range should not be a
problem. If you experience low or no signal strength in areas of
your home that you wish to access, consider positioning the
Access Point in a location directly between the Residential
Gateways and/or Computers that will be connected. Additional
Access Points can be connected to provide better coverage in
rooms where the signal does not appear as strong as desired.
