Field Name Description
RADIUS Server Allows you to enter the IP address of the RADIUS
server used for authentication and encryption key
derivation.
This field is used with 802.1x and WPA Network
Authentication.
The factory default for this field is 0.0.0.0.
RADIUS Port Determines the port number of the RADIUS server.
The port number is usually 1812 (factory default) or
1645, depending on the server used.

This field is used with 802.1x and WPA Network
Authentication.
Data Encryption Allows you to enable data encryption to help secure
the data that is sent over your wireless network.
WEP 128-bit (factory default)
– 128-bit or-64 bit static key data encryption
can be selected when the network is
configured to have no authentication.
– 128-bit static key data encryption is
automatically selected when 802.1x network
authentication is enabled.
Note: Static key authentication uses one of the
four encryption keys, as define below, to encrypt
your data. You must manually change keys. The
keys do not change or rotate automatically as
they do with TKIP.
TKIP (Temporal Key Integrity Protocol) data
encryption is automatically enabled when WPA
and WPA-PSK network authentication is
enabled.
Notes:
64-bit and 40-bit encryption are two different
names for the same encryption
128-bit and 104-bit encryption are two different
names for the same encryption
