2-10 WLAN Networking
Open authentication mode is implemented for ease-of-use and when security is not an issue. The wireless
station and the AP do not share a secret key. Thus the wireless stations can associate with any AP and listen
to any data transmitted plaintext.
Shared authentication mode involves a shared secret key to authenticate the wireless station to the AP.
This requires you to enable the wireless LAN security and use same settings on both the wireless station
and the AP.
