– TKIP—the encryption protocol used for WPA It implements a more
efficient mechanism of key change management in comparison with WEP;
– AES—128-bit block encryption algorithm with 128/192/256-bit key,
generally used for WPA2).
– Mixed WPA2/WPA—includes a combination of WPA2/WPA (this encryption mode uses WPA2
and WPA protocols, requires the utilization of a RADIUS authentication server);
 WPA2 Preauthentication—pre-authentication of the wireless client in other
wireless access points in the specified range. During authentication,
communication is provided by the current wireless access point;
 Network Re-auth Interval—time interval for repeated authentication. The
parameter defines how often the access points sends an authentication message to
clients and requires a reply with valid authentication data;
 WPA Group Rekey Interval—the period of time (in seconds) between automatic
changes of WPA encryption keys used to strengthen wireless network security. If
you don't need to change encryption keys, enter null value into the field.
 RADIUS Server IP Address—IP address of the RADIUS server;
 RADIUS Port—port number of the RADIUS server. The default port is 1812;
 RADIUS key—a secret key for access to the RADIUS server;
 WPA/WAPI Encryption—selects a WPA/WAPI data encryption method: TKIP+AES,
AES:

– AES—128-bit block encryption algorithm with 128/192/256-bit key,
generally used for WPA2);
– Mixed WPA2/WPA-PSK—includes a combination of WPA2/WPA-PSK (this encryption mode
uses WPA2-PSK and WPA-PSK protocols, requires the utilization of a RADIUS authentication server)
 WPA/WAPI Password—a secret phrase Sets a password; a string of 8-63 ASCII
characters. To view a secret phrase, click Click here to display link, and password
will be shown in a pop-up window.
Default network key corresponds to device serial number. Serial number
is printed on a sticker, which is located on device housing. When
changing a password, you have to specify a 10-character combination.
Password should contain numbers and Latin characters in upper and
lower case.
 WPA Group Rekey Interval—the period of time (in seconds) between automatic
changes of WPA encryption keys used to strengthen wireless network security. If
you don't need to change encryption keys, enter null value into the field.

Make sure that the wireless adapter of a computer supports selected encryption type.
The most secure protection of a wireless channel is reached by joint operation of access point and
