Using the Wireless LAN connection

WLAN Settings dialog box

To deactivate WLAN connectivity, select Disable for the Status field drop-down box on the WLAN Settings dialog.

By default, WLAN uses theIEEE802.11b/g standard technology for WLAN connectivity. The standard includes the Wired Equivalent Privacy (WEP) encryption method, which is a security protocol and WiFi Protected Access.

To use IEEE802.11b or IEEE802.11g WLAN connectivity standard only, select them from the Mode field drop-down box.

✍Wireless LAN devices using the IEEE802.11a standard and the ones using the IEEE802.11b or g standard cannot communicate because the frequencies are different. Wireless LAN devices using the IEEE802.11g standard can only communicate with a device using the IEEE802.11b standard, not with the IEEE802.11a standard.

✍IEEE802.11b: The standard speed is 11 Mbps, or about 30 to 100 times faster than a standard dial up.

✍IEEE802.11g: The standard speed is 54 Mbps, or about 5 times faster than a Wireless LAN device using the IEEE802.11b standard.
