When using WPA or WPA2 authentication, these WPA
encryption modes can be set: TKIP, AES, or TKIP + AES. AES
(Advanced Encryption Standard) provides the strongest
encryption, while TKIP (Temporal Key Integrity Protocol)
provides strong encryption with improved compatibility. The
TKIP + AES mode allows both TKIP and AES-capable clients to
connect.
Sets the WPA Pre-Shared Key (PSK). This is either an 8-63
ASCII character string or a 64-digit hex number. This is
specified when the Network Authentication method is WPA-
PSK.
Show Key - When selected, the WPA Pre-Shared Key is
displayed.
Sets the RADIUS server IP address to use for client
authentication using the dotted-decimal format
(xxx.xxx.xxx.xxx).
Sets the UDP port number of the RADIUS server. The default
is 1812.
Sets the shared secret for the RADIUS connection. The key is
a 0 to 255 character ASCII string.
Sets the WPA Group Rekey Interval in seconds. Set to zero to
disable periodic rekeying.
The re-authentication interval is the amount of time the
wireless router can wait before re-establishing authentication
with the CPE.
WEP Encryption enables or disables Wired Equivalent Privacy
encryption.
The WEP protocol uses the Shared Key Authentication
protocol where the CPE sends an authentication request to
the access point. Then the access point sends a challenge text
to the CPE.
The CPE uses either the 64-bit or 128-bit key to encrypt the
challenge text and sends the encrypted text to the access
point. The access point decrypts the encrypted text and then
compares the decrypted message with the original challenge
text. If they are the same, the access point lets the CPE
connect; if it doesn't match, then the access point does not let
the CPE connect.
