WIreless LAN User’s Guide
Access Point (Infrastructure) Mode (See Figure 2)
Infrastructure mode refers to a wireless network in
which devices communicate with each other by first
going through an Access Point (AP). In infrastructure
mode, wireless devices can communicate with each
other or can communicate with a wired network. Most
corporate wireless LANs operate in infrastructure mode
because they require access to the wired LAN in order to
use services such as file servers or printers.
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:
■
For optimum wireless communications, it recom-
mended that operation of the wireless LAN module
occur within 25 meters of the Access Point. Wireless
range is dependent on a multitude of factors including
number of obstructions, walls, type of construction
material, reflective objects, etc.
■
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.
■
Broadcast stations or wireless communication equip-
ment that operate in the 2.4GHz or 5GHz RF Fre-
quency band may interfere with the operation of the
wireless LAN module. Increasing of transmit power or
relocating Access Points may be necessary to combat
the effects of the interference.
