The wireless LAN access point is approved
to create a wireless LAN network to send
data and e-mail messages, to browse on
the Internet, and to establish connections
with other computers.
Data connections can be made from most
locations where your wireless LAN card
operates. However, it is recommended that
you move the wireless LAN access point to
a location where the strongest possible
network signal can be provided to wireless
LAN users. When the signal is strong, data
transmission is efficient.
The following factors may impair wireless
connections:
Noise
Radio interference from electronic
appliances and equipment, as well as from
other wireless devices in areas where
wireless devices are prevalent.
Handover
As the wireless LAN card user moves from
one network cell to another, the signal
strength of the channel drops and the
network may hand the user over to a
different cell and frequency, where the
signal is stronger. A cell handover may
also occur when the user is stationary due
to varying network traffic loads.
Electrostatic discharge
A discharge of static electricity from a
finger or a conductor may cause erroneous
functions in electric devices. The discharge
may result in unstable software operation.
Network connections may become
unreliable, data may be corrupted, and the
transmission halted. In this case, end the
existing connection (if any) and remove
the wireless LAN card from the PC card
slot. Then insert the wireless LAN card into
the PC card slot and try again.
Dead spots and dropouts
Dead spots are areas where radio signals
cannot be received. Dropouts occur when
the wireless LAN card user passes through
an area where the radio signal is blocked
or reduced by geographic or structural
obstructions.
Signal impairment
Distance and obstacles can cause out-of-
phase reflected signals that result in a loss
of signal strength.
Low signal strength
Due to either distance or obstacles, the
radio signal strength from a network cell
may not be strong or stable enough to
provide a reliable wireless connection for
communication. Therefore, to ensure the
best possible communication, remember to
consider the following points:
• Data connection works best when the
wireless LAN card is in a stationary
position.
• Do not place the wireless LAN card
on a metal surface.
