Fragment Threshold

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.

 

RTS Threshold

This value should remain at its default setting of

 

4096. Should you encounter inconsistent data

 

flow, only minor modifications of this value are

 

recommended.

 

Preamble

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.)

Authentication

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.

Retry limits

You can set the number of retries if no

 

acknowledgement appears from the receiving

 

station.

 

Antennas
