WPA2 / WPA with Pre-shared key (PSK)
WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic
keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The
new standard WPA2 uses AES for the encryption.
WPA-PSK is a special WPA mode for users at home and in small companies without a
company authentication server. Encryption keys are automatically generated with the
Pre-shared key, automatically changed ( "rekeying") and authenticated between the
devices after a certain period of time (
Rekey Interval ).
ì
Select the option WPA2-PSK if it is supported by all components in your wireless

or
ì
Select the option WPA2-PSK / WPA-PSK if some or all components in your wireless

ì

and confirm it by repeating the entry.
You must also set the same Pre-shared key for all wirelessly connected PCs.

Please remember:
Every PC (network adapter) that requires access to a wireless network protected by
WPA must also support WPA. To find out whether and how you can use WPA on your
PC, read your network adapter's operating instructions.
