5 THE TECHNICOLOR GATEWAY WIRELESS ACCESS POINT
E-DOC-CTC-20100728-0008 v2.0
5.3 Securing Your Wireless Connection
Introduction
You can protect the wireless communication between the wireless clients and your Technicolor Gateway with a wireless key.
This means that:
Only clients which use the correct Network Name (SSID) and wireless key can connect to your network.
All data passing through your wireless access point is secured and encrypted.
Encryption types
Over the years a number of encryption types have been developed. The list below gives you an overview of the supported
encryption types ordered by descending security level; you will find the highest level of security at the top of the list:
For Enterprise environment(s):
RADIUS Server (WPA):
Wireless clients first need to authenticate to the Remote Authentication Dial In User Service (RADIUS) server. The
RADIUS server then provides the wireless key that must be used to encrypt its data. The RADIUS server regularly
updates this key at a specified interval.
If you do not have a RADIUS server in your network, use on the of the encryption types for home and small office
environment.
For home or small office environment:
WPA-PSK Encryption:
The wireless connection is secured with a pre-shared key that has been defined by the user. Wireless clients must be
configured with this key before they can connect to the Technicolor Gateway. The Technicolor Gateway supports the
following WPA versions (ordered by descending security):
WPA2:
The most recent and most secure version of WPA. Choose this version if you are sure that all your wireless clients
support WPA2.
WPA+WPA2:
This is a mixed mode. In this mode WPA2, is the preferred encryption type but wireless clients do not support WPA2,
can still use WPA as encryption type. Choose this option if not all of your wireless clients support WPA2 or if you are
not sure. Wireless clients that support WPA2 will use WPA2, the others will use WPA.
WPA:
The first version of WPA. Choose this option if you are sure that none of your wireless clients support WPA2.
WEP Encryption:
The least safe encryption type used for wireless connections. Like WPA-PSK it uses a user-defined key, but WEP has
been proven to have security issues.
If you want to configure WPA2 on the built-in wireless utility of Windows XP Service Pack 2 (SP2), you first have
to:
Upgrade your Windows XP to Service Pack 3.

Although the Technicolor Gateway allows you to use WEP or no security, we strongly advise against using one of
them! Use WPA(2)-PSK or RADIUS instead.
