To fragment MSDU or MMPDU into small sizes of 
frames for increasing the reliability of frame (The 
maximum value of 4096 means no fragmentation is 
needed) transmission. The performance will be 
decreased as well, thus a noisy environment is 
recommended.   

This value should remain at its default setting of 
4096.  Should you encounter inconsistent data 
flow, only minor modifications of this value are 
recommended. 

A preamble is a signal used in wireless environment 
to synchronize the transmitting timing including 
Synchronization and Start frame delimiter. (Note: If 
you want to change the Preamble type into Long or 
Short, please check the setting of AP.) 

The authentication type defines configuration 
options for the sharing of wireless networks to 
verify identity and access privileges of roaming 
wireless network cards.   
You may choose between Open System,  Shared 
Key, and Auto Switch.  
Open System: If the Access Point is using "Open 

System" authentication, then the wireless adapter 
will need to be set to the same authentication type.   

Shared Key:  Shared Key is when both the sender 

and the recipient share a secret key. 

Auto Switch: Select Auto Switch for the adapter to 
select the Authentication type automatically 
depending on the Access Point Authentication type. 

You can set the number of retries if no 
acknowledgement appears from the receiving 
station. 

To set the type of the antenna 
Tx Antenna：Antenna2 (Use    the factory default) 
RX Antenna：Both (Use  the factory default)
