z Peer-to-Peer (Ad-Hoc) and Access Point (Infrastructure) modes
support
z WEP (Wired Equivalent Privacy) 64/128-bit data encryption
z IEEE 802.11a/b/g standard compliance

NOTE: 802.11g mode is backward compatible with 802.11b mode.
To take advantage of the WLAN feature, make sure that the PROSet
driver is installed correctly. (See chapter 6 for details.) If your WLAN
card was provided by your dealer instead of the computer manufacturer,
contact your dealer for the correct driver to use.
Turning Off/On the WLAN Radio
NOTE: The FAA (Federal Aviation Agency) has deemed it unsafe to operate wireless
devices in aircraft as this may interfere with flight safety. Remember to turn off wireless
LAN when using your computer in the airplane.
Your computer has a built-in WLAN hot key to switch the WLAN on/off
(see “Hot Keys” in Chapter 2).
