Access Point (Infrastructure) Mode (See Figure A-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 Wireless Module

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 wireless LAN has been configured to support the operating system with which your system shipped.

FOR BETTER COMMUNICATIONS

This personal computer may not operate properly due to the operating environment. It is highly recommended that you observe the following precautions when using your wireless LAN module:

■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 sus- ceptible 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.

STOPPING TRANSMISSION

To use this product inside hospitals, clinics, or airplanes, or in other places where the use of electronic equipment is regulated, stop the transmission of radio waves from the wireless LAN beforehand.

Deactivation using the wireless switch

The transmission of radio waves from the wireless LAN can be stopped by setting the wireless switch to the Off position. Note that the wireless LAN On/Off switch has no effect on non-wireless LAN models.

(See Figure A-3 for Wireless LAN switch location.)
