RADIUS Server authentication
RADIUS servers allow external authentication of users by means of a remote authentica-
tion database. The remote authentication database is maintained by a Remote Authentica-
tion Dial-In User Service (RADIUS) server. In conjunction with Wireless User Authentication,
you can use a RADIUS server database to authenticate users seeking access to the wire-
less services, as well as the authorized user list maintained locally within the Gateway.
If you select
WPA-802.1x
, the screen expands.
Click the
Confi
gure RADIUS Ser
ver
button.

The Configure RADIUS Server screen appears.
Enter your RADIUS Server information in the appropriate fields:
RADIUS Server Addr/Name:
The default RADIUS server name or IP address that you
want to use.
RADIUS Server Secret:
The RADIUS secret key used by this server. The shared secret
should have the same characteristics as a normal password.
Alt RADIUS Server Addr/Name:
An alternate RADIUS server name or IP address, if
available.
Alt RADIUS Server Secret:
The RADIUS secret key used by this alternate server. The
shared secret should have the same characteristics as a normal password.
RADIUS Server Port:
The port on which the RADIUS server is listening, typically, the
default 1812.

WPA-PSK
One of the easiest ways to enable Privacy on your Wireless network is by selecting
WPA-PSK
(Wi-Fi Protected Access) from the pull-down menu.
The screen expands to allow you to enter a
Pre Shared Key
. The key can be between 8
and 63 characters, but for best security it should be at least 20 characters. When you have
entered your key, click the
Sa
ve Chang
es
button.

WEP-Manual
Alternatively, you can enable WEP (Wired Equivalent Privacy) encryption by selecting
WEP-Manual
from the Privacy pull-down menu.
You can provide a level of data security by enabling WEP (Wired Equivalent Privacy) for
encryption of network data. You can enable 40-, 128-, or 256-bit WEP Encryption (depend-
ing on the capability of your client wireless card) for IP traffic on your LAN.

WEP - Manual
allows you to enter your own encryption keys manually. This is a difficult
process, but only needs to be done once. Avoid the temptation to enter all the same char-
acters.
Encryption Key Size #1 – #4
: Selects the length of each encryption key. The longer the
key, the stronger the encryption and the more difficult it is to break the encryption.
Encryption Key #1 – #4
: The encryption keys. You enter keys using hexadecimal digits.
For 40/64bit encryption, you need ten digits; 26 digits for 128bit, and 58 digits for 256bit
WEP. Hexadecimal characters are 0 – 9, and a – f.
Examples:
40bit: 02468ACE02
128bit: 0123456789ABCDEF0123456789
256bit:
592CA140F0A238B0C61AE162F592CA140F0A238B0C61AE162F21A09C
Use WEP encryption key (1 – 4) #
: Specifies which key the Gateway will use to encrypt
transmitted traffic. The default is key #1.
Click the click
Sa

es
button.
Any WEP-enabled client must have an identical key of the same length as the Router, in
order to successfully receive and decrypt the traffic. Similarly, the client also has a
‘default’ key that it uses to encrypt its transmissions. In order for the Router to receive the
client’s data, it must likewise have the identical key of the same length.
