P2612HNU Fx Support Notes

What is WPA-PSK?

WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) can be used if user do not have a
Radius server but still want to benefit from it. Because WPA-PSK only requires a
single password to be entered on wireless AP/gateway and wireless client. As long
as the passwords match, a client will be granted access to the WLAN.

What is WPA2?

WPA2 (Wi-Fi Protected Access 2) which security is a higher level then WPA, cause it
brings AES-base algorithm and CCMP in it and offers stronger encryption then WPA
uses (TKIP). WPA2 encryption keys that are used for each client on the network are
unique and specific to that client. Eventually, each packet which is sent over the air is
encrypted with a unique key. The higher security is enhanced with the use of a new
and unique encryption key because there is no key reuse.
