Figure 2. Infrastructure Mode Network
Internet
Wireless LAN
To improve this situation, you can use a wireless LAN
access point, which is sold separately. The wireless LAN
network is in the "Infrastructure mode" when it uses an
access point, and such a connection is called the "Infra-
structure Network."
By using an access point, you can set and use a different
communication channel for each network group. Each
channel is given a different radio frequency, and it
eliminates the collision of communications and provides
a more stable communications environment.
How to Handle This Device
The Integrated Wireless LAN device is already installed
in your mobile computer. Under normal circumstances,
it should not be necessary for you to remove or re-install
it. The LAN has been configured to support the oper-
ating system with which your system shipped.

FOR BETTER COMMUNICATIONS

This personal computer may not operate properly due to
the operating environment. Strictly observe the
following precautions when installing the main unit of
the computer:
Since this personal computer and equipment compli-
ant with IEEE802.11a differ in operation frequency, it
is not possible to communicate between both.
The recommended wireless communications distance
is within a line-of-sight radius of 25 meters. For rea-
ADSL modem,
cable modem,
or similar

Wired LAN
Access Point*
* An optional hub for a wired
LAN may be required depending
upon the type of access point used.
sons related to the characteristics of the wireless LAN,
however, the actual communications distance depends
on the structure of the building in which the wireless
LAN function is to be used, the presence/absence of
obstructions, the types of software to be used, installa-
tion status, radio-wave status, or other operating con-
ditions. Decreases in communications speed or a
communications failure may also occur.
Distance the main unit of this personal computer is
from other electric appliances. If the main unit of the
person computer is installed near a powered-on elec-
tric appliance, the computer may not be able to com-
municate properly or trouble may occur in the electric
appliance.
If the computer is unable to communicate properly,
change the channel to be used or the installation loca-
tion. During the use of a microwave oven or other
equipment generating strong high-frequency energy,
in particular, the personal computer may be highly
susceptible to the energy and unable to communicate
properly.
If a broadcasting station or wireless communications
equipment is present nearby and this prevents the
computer from communicating properly, moving the
main unit of the computer is suggested. Radio inter-
ference may also occur if the intensity of ambient
radio waves is too high.
