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.
