business of large residential home deployment, it may be more
beneficial to have more than one access point with overlapping
coverage.
2. Be aware of the direct line between Access Points, Residential
Gateways, and Computers - A wall that is 1.5 feet thick, at a 45
degree angle appears to be almost 3 feet thick. At a 2 degree angle it
looks over 42 feet 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 negative 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.
5. Keep your product away (at least 3-6 feet) from electrical devices that

Additional Access Points can be connected to provide better coverage in
rooms where the signal does not appear as strong as desired.
Using radio frequency (RF) technology, WLANs transmit and receive data
over the air, minimizing the need for wired connections. Thus, WLANs
combine data connectivity with user mobility, and, through simplified
configuration, enable movable LANs.
