Preamble is used to signal that data is coming to the receiver.  

Short preamble increases performance as less time sending preamble means more time for 
sending data. All IEEE 802.11b/g compliant wireless adapters support long preamble, but not 
all support short preamble. 

Select Auto to have the G-170S automatically use short preamble when access point or 
wireless stations support it; otherwise the G-170S uses long preamble. 

Note: The G-170S and the access point/wireless stations MUST use the same 

preamble mode in order to communicate.
