3.4 Changing the wireless security settings
Introduction
We recommend you to protect all wireless communication between the wireless clients and your TG-1
Gateway with a wireless key. This means that:
Only clients that use the correct Network Name (SSID) and wireless key can connect to your network.
All data passing through your wireless access point is secured by encryption.
Encryption types
Over the years a number of encryption methods have been developed. The list below gives you an
overview of the encryption types supported by the TG-1 Gateway and ordered by descending security
level; you will find the highest level of security at the top of the list:
WPA-Personal (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 TG-1 Gateway. The TG-1
Gateway supports the following WPA-PSK versions (ordered by descending security):
WPA2 PSK:
the most recent and most secure version of WPA-PSK.
Choose this version if you are sure that all your wireless clients support WPA2-PSK.
WPA+WPA2 PSK
: this is a mixed mode.
In this mode WPA2-PSK, is the preferred encryption type but wireless clients do not support
WPA2-PSK can still use WPA-PSK as encryption type.
Choose this option if not all of your wireless clients support WPA2-PSK or if you are not sure. Wireless
clients that support WPA2-PSK will use WPA2-PSK, the others will use WPA-PSK.
WPA-Enterprise (WPA) encryption:
Wireless clients will 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. The TG-1 Gateway supports the following WPA-
PSK versions (ordered by descending security):
WPA2:
the most recent and most secure version of WPA-Enterprise.
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.
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.
Configuration
To secure your wireless network with:
WPA-PSK encryption, continue with
“3.4.1 Configuring WPA-PSK encryption” on page 25
WPA encryption (via RADIUS), continue with
“3.4.2 Configuring WPA encryption” on page 26
Although the TG-1 Gateway allows you to use WEP or no security, we strongly advise against
using one of them!
