WPA2:
WPA2 provides a stronger encryption mechanism than WPA. WPA2 is the second
generation of WPA security, providing personal and enterprise users with a high level of
assurance that only authorized users can access to their wireless network. There is no difference
between WPA and WPA2. The only difference is that WPA2 provides a stronger data encryption
via the AES, contrast to WPA, which uses Temporal Key Integrity Protocol (TKIP). Choose WPA2
if needed from Authentication Mode.
WPA2-PSK:
Like WPA, WPA2-Personal offers authentication via a pre-shared key. Pre-shared
key is usually used for Personal authentication. Personal mode requires only an access point and
client on the network. Similarly, you need to type a mixture of numbers and letters in the
Pre-shared key
section of this menu. You may input either 8-63 ASCII characters or 64 HEX
characters. Choose WPA2-PSK if needed from Authentication Mode.
