Wireless Mode 
802.11 B/G mix – If you have a mix of 802.11b and 802.11g 
wireless stations in your network, it is recommended to setting the 
card to this mode. This mode is also the default setting. 
 
802.11 B or G only – This card can be compatible with both 
802.11g and 802.11b wireless stations. If there are only 802.11b 
wireless stations in the network, you can set the card to this mode.
The same goes with 802.11g only wireless stations. 
 
 
Turbo Mode 
Turbo Mode enables the card to deliver the better throughput in 
the same period and environment. 
 
 
B/G Protection 
If you have a mix of 802.11b and 802.11g wireless stations in the 
network, it is recommended that you enable the protection 
mechanism. This mechanism can decrease the rate of data 
collisions between 802.11b and 802.11g wireless stations. When 
the protection mode is enabled, the throughput of the card will be 
a little lower due to more complex data packets that must be 
transmitted. 
Auto – Based on the status of the network and automatically 
disable/enable protection mode. 
 
On – Always enable the protection mode. 
 
Off – Always disable the protection mode. 
Fast Roaming 
These settings should only be used for advanced system 
administrators only. 
 
 
Tx Rate 
There are several options including 
Auto/1/2/5.5/11/6/9/12/18/24/36/48/54Mbps for you to select. 
When the “Auto” is selected, the device will choose the most 
suitable transmission rate automatically. The higher data rate you 
designated in the network, the shorter distance is allowed 
between the card and the wireless stations. 
 
When the wireless mode is “802.11 B only”, the maximum data 
rate is 11Mbps (11b) so that there are only “Auto/1/2/5.5/11Mbps” 
options you can select. 
 
 
Turn Off RF Button 
If you want to turn off the radio of the card temporarily, click this 
button. To turn on the radio, click this button again.
