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.
