Wireless Modem Router User's Manual

For 802.1X Wireless Network
When a wireless client requests to access a network, it is required to be
authenticated by a central authentication server (RADIUS Server). Only an
authenticated user can be granted by the network access and thereby those
unauthorized will be blocked.
Wireless Security:
Choose 802.1x as the authentication
protocol, your data transmission
between the router and the clients will
be protected with the settings that you
set in this web page.
RADIUS Server IP Address:
RADIUS Server is a protocol for
carrying authentication, authorization,
and configuration information between
a Network Access Server which
desires to authenticate its links and a
shared Authentication Server. Please
enter the IP Address for the RADIUS
Server.
RADIUS UDP Port:
Port 1812 is the reserved RADIUS-
authentication port described in RFC
2138. Earlier AP (RADIUS clients) use
port 1945. The default value will be
shown on this box. You can keep and
use it.
RADIUS Shared Secret:
A shared secret is like a password,
which is used between RADIUS
Server and the specific AP (RADIUS
client) to verify identity. Both RADIUS
Server and the AP (RADIUS client)
must use the same shared secret for
successful communication. Enter the
words for the share secret.
After finishing the settings, click Apply
for activation.
