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 stations in the Wireless LAN network without through an
Access Point or Router.
TX Power
If you want to lower the transmit power of the adapter for saving the
power of the system, you can select the lower percentages from the
list. The lower power will cause the lower signal strength and the
coverage range.
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 and Long Preamble. If
“Auto“ mode is selected, the adapter will auto switch the preamble
mode depending on the wireless devices the adapter 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 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 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.
