–
AES—128-bit block encryption algorithm with 128/192/256-bit key,
generally used for WPA2;
–
WPA2-PSK— enables WPA2-PSK (the mode uses the WPA2 protocol but does not require the
RADIUS authentication server);

WPA/WAPI passphrase— secret phrase. Sets a password; a string of 8–63 ASCII
characters. Follow the Click here to display link to show the secret phrase; the
password will be displayed in a pop-up window.
The network key corresponds to the device serial number by default.
The serial number is labelled on the device housing. When you change
the password, you will need to specify a combination of 10 characters.
The password must contain digits and Latin characters in upper and
lower cases.

WPA Group Rekey Interval— the period of time (in seconds) between automatic
changes of WPA encryption keys; used to strengthen wireless network security. If
no key changes are required, set this field to 0.

WPA/WAPI Encryption— select a WPA/WAPI data encryption method: TKIP+AES,
AES:
– TKIP—encryption protocol for WPA. It enables more efficient
management of key changes compared to 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 requires a
RADIUS authentication server and uses WPA2 and WPA protocols);

WPA2 Preauthentication – pre-authentication of the wireless client in other
wireless access points in the specified range. Connection is established at the
current wireless access point during the verification

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 correct 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
no key changes are required, set this field to 0.

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— secret key for access to the RADIUS server;

WPA/WAPI Encryption— select a WPA/WAPI data encryption method: TKIP+AES,
AES:
– TKIP—encryption protocol for WPA. It enables more efficient
management of key changes compared to WEP;
– 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 a RADIUS authentication server).

WPA/WAPI passphrase— secret phrase. Sets a password; a string of 8–63 ASCII
characters. Follow the Click here to display link to show the secret phrase; the
password will be displayed in a pop-up window.
