I use a Linksys AP for my tests.I got the Answer for my question.
Yeahhhh...
I think in Mixed Mode 802.11g AP doesnt use Short Preambles.
But when there is no Non-ERP client associated they tend to use Short slot time.
In 802.11G Mixed mode and no NON-ERP
-----------------------------------------------
short preamble =0
slot time = 9ms
Barker mode = 0
Non ERP = 0
Use protection =0
In 802.11G Only mode
--------------------------
short preamble =1
slot time = 9ms
Barker mode = 0
Non ERP = 0
Use protection =0
In 802.11G Mixed mode with a NON-ERP which is only Long Preamble
-----------------------------------------------------------------------------Capable
----------
short preamble =0
slot time = 20 ms
Barker mode = 1
Non ERP = 1
Use Protection =1
In 802.11G Mixed mode with a NON-ERP ( Long and short preamble Capable but currently using long)
----------------------------------------
short preamble =0
slot time = 20 ms
Barker mode = 0
Non ERP = 1
Use protection = 1
Good that i found out the answer myself and didnt waste others time .
