Before Using the Wireless LAN

This manual describes the procedures required to prop-
erly set up and configure the optional integrated Wire-
less LAN Mini-PCI device (referred to as "WLAN
device" in the rest of the manual). Before using the
WLAN device, read this manual carefully to ensure it's
correct operation. Keep this manual in a safe place for
future reference.

WIRELESS LAN DEVICE COVERED BY THIS
DOCUMENT

This document is applicable to systems containing the
following WLAN device:

■

Atheros SuperAG (802.11a+b/g)

CHARACTERISTICS OF THE WLAN DEVICE

■

The WLAN device is a Mini-PCI card attached to the

main board of the mobile computer.

■

The WLAN device operates in license-free RF bands,

eliminating the need to procure an FCC operating
license. The WLAN operates in the 2.4GHz Industrial,
Scientific, and Medical (ISM) RF band and the lower,
middle, and upper bands of the 5GHz Unlicensed
National Information Infrastructure (UNII) bands.

■

The Atheros SuperAG device is capable of three oper-

ating modes, IEEE802.11a, IEEE802.11b, and
IEEE802.11g.

■

The WLAN device is Wi-Fi certified and operate (as

applicable) at a the maximum data rate 54 Mbps in
IEEE802.11a or IEEE802.11g mode; and 11 Mbps in
IEEE802.11b mode.

■

The WLAN device supports the following encryption

methods - WEP, TKIP, CKIP, and AES encryption.

■

The Wireless LAN device is compliant with the

following standards: WPA, WPA2, CCX1.0, CCX2.0,
CCX3.0, and CCX4.0.

WIRELESS LAN MODES USING THIS DEVICE

Ad Hoc Mode

(See Figure A-1)

"Ad Hoc Mode" refers to a wireless

network architecture where wireless network connec-
tivity between multiple computers is established without
a central wireless network device, typically known as
Access Point(s). Connectivity is accomplished using only
client devices in a peer-to-peer fashion. That is why Ad
Hoc networks are also known as peer-to-peer networks.
Ad Hoc networks are an easy and inexpensive method
for establishing network connectivity between multiple
computers.

Ad Hoc mode requires that the SSID, network authenti-
cation, and encryption key settings are identically
configured on all computers in the Ad Hoc network.

Access Point (Infrastructure) Mode

(See Figure A-2)

Infrastructure mode refers to a wireless

network architecture in which devices communicate
with wireless or wired network devices by communi-
cating through an Access Point. In infrastructure mode,
wireless devices can communicate with each other or
with a wired network. Corporate wireless networks
operate in infrastructure mode because they require
access to the WLAN in order to access services, devices,
and computers (e.g., file servers, printers, databases).

How to Handle This Device

The WLAN device is an optional device that may come
pre-installed in your mobile computer. Under normal
circumstances, it should not be necessary for you to
remove or re-install it. The Operating System that your
mobile computer comes with has been pre-configured to
support the WLAN device.
