Parameter Description

Network Type Infrastructure – This operation mode requires the presence of an

802.11 Access Point. All communication is done via the Access

Point or Router.

Ad-Hoc – Select this mode if you want to connect to another

wireless station in the Wireless LAN network without going

through an Access Point or Router. Peer to Peer.

Transmit Power If you wish to lower the transmit power of the card to save the

power of your system, you can select the lower percentages from

the list.

11B Preamble Type The preamble defines the length of the CRC block for

communication among wireless stations. This option is only active

in the Ad Hoc network.

There are two modes including Auto and Long Preamble. If

“Auto“ mode is selected, the card will auto switch the preamble

mode depending on the wireless stations which the card is

connecting to.

RTS Threshold Minimum packet size required for an RTS (Request To Send). For

packets smaller than this threshold, an RTS is not sent and the

packet is transmitted directly to the wireless network. Select a

setting within a range of 0 to 2312 bytes. Minor change is

recommended.

Fragment Threshold The value defines the maximum size of packets; any packet size

larger than the value will be fragmented. If you have decreased

this value and experience high packet error rates, you can

increase it again, but it will likely decrease overall network

performance. Select a setting within a range of 256 to 2312 bytes.

Minor change is recommended.

Channel This setting is only available for Ad Hoc mode. Select the number

of the radio channel used for the networking. The channel setting

should be the same with the network you are connecting to.
