Security Settings - WPA-PSK
Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should
be used if possible. The PSK (Pre-shared Key) must be entered on each Wireless station. The
256Bit encryption key is derived from the PSK, and changes frequently.

TKIP.
Group Key Update This refers to the key used for broadcast transmissions. Enable
this if you want the keys to be updated regularly.

updated. Enter the desired value.
Update Group key

because UAM is not available with WPA-PSK. The Configure
button for this feature will also be disabled.
