card to this mode. This mode is also the default setting.

 

802.11 B 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.

 

802.11 G only – This card can be compatible with both 802.11g

 

and 802.11b wireless stations. If there are only 802.11g wireless

 

stations in the network, you can set the card to this mode.

Select Your Country Region Code

The available channel differs from different countries. For

 

example: USA (FCC) is channel 1-11, Europe (ETSI) is channel

 

1-13. The operating frequency channel will be restricted to the

 

country user located before importing. If you are in different

 

country, you have to adjust the channel setting to comply the

 

regulation of the country.

B/G Protection

If you have a mix of 802.11b and 802.11g wireless stations in the

 

network, it is recommended to enable the protection mechanism.

 

This mechanism can decrease the rate of data collision 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

 

many of frame traffic should 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.

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.

Tx BURST

Tx Burst enables the card to deliver the better throughput in the

 

same period and environment.
