1- PL_WLN_WPA_ALGORITHM_AES: AES algorithm (also referred to as CCMP).
GA1000: A string containing new WPA key (must be 16 characters long). The key is not the password to your access point. The key is calculated from the password. The math involved is complex and is better left to the WLN library. WA2000: A string containing the password itself. The WA2000 performs the WPA key calculation internally.
