stations. If there are only 802.11b wireless stations in the network, you can set the card
to this 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 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.
Preamble: The preamble defines the length of the CRC block for communication among
wireless devices. This option is only active in the Ad Hoc network. There are two modes
including Auto, Long and Short Preamble. If “Auto” mode is selected, the adapter will auto
switch the preamble mode depending on the wireless devices 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 2347 bytes. Minor change is
recommended.
Fragment Threshold: The value defines the maximum size of packets; any packet size larger
than 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 2346 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.
