Authentication Type:
Open System: with the same WEP key between the stations, the
stations don’t need to be authenticated, and this algorithm was set to

by transferring a challenge text which will be acknowledge by both
side of the stations. In order to choose which authentication algorithm
will be used, you must know which one the station supports this
algorithm first.
