WPA-PSK or WPA-NONE Security Mode:
"WPA-shared key" (for an infrastructure network) or
"WPA-None" (enables WPA security for your ad hoc
network) requires users to set the advanced encryption
methods, i.e. TKIP and enter a set of shared key.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal
key every 10,000 packets. This insures much greater security than
the standard WEP security.
