Connecting Your Wireless Client without WPS
Before you start
Before you can connect a computer to your wireless network you need to know which Network Name (SSID)
and wireless encryption your Thomson Gateway is using.
What Network Name (SSID) is the Thomson Gateway using?
If you did not change the SSID manually, your Thomson Gateway uses the SSID that is printed on the bottom
panel label of your Thomson Gateway.
What wireless security is the Thomson Gateway using?
You have not yet configured your Thomson Gateway
In this case, no encryption is used.
You have already configured your Thomson Gateway
If you have configured the wireless security settings through the Thomson Gateway GUI, the encryption key/
passphrase is the one you typed in the the
Encryption Key
textbox.
Forgot your wireless settings?
If you have changed the wireless settings manually and you can’t remember your settings, try one of the
following:
If one of your computers is already connected to your network:
1
Browse to the
Thomson Gateway GUI
on a computer that is already connected to your network.
2
On the
Home Network
menu, click
Wireless
.
3
In the upper-right corner, click
Details
.
4
Under:
²
Configuration
, you can find the network name (SSID).
²
Security
, you can find the encryption.
If none of your computers is connected to your network, connect a computer using a wired connection and
follow the procedure above to find out what your wireless settings are.
Another option is to reset your Thomson Gateway and configure it all over again. For more information, see
”7.2 Reset to Factory Defaults” on page 91
.
Procedure
Configure your computer with the same wireless settings as your Thomson Gateway. For more information,
consult the help of your wireless client.

Securing Your Wireless Connection
Introduction
By using encryption, communication between the wireless clients and your Thomson Gateway is protected
by a passphrase. Only clients which use the correct network name (SSID) and passphrase can connect to your
network.
Encryption methods
During the years a number of encryption types have been developed. The list below gives you an overview of
the supported encryption types ordered by security level, you will find the highest level of security at the top
of the list:
±
WPA-PSK Encryption:
The wireless data is being encrypted with a user-defined key. Wireless clients must be configured with
this key before they can connect to the Thomson Gateway.
±
WEP Encryption:
The first encryption type used for wireless connections. Like WPA-PSK it uses a user-defined key, but WEP
has been proven to have some security issues.
We strongly recommend you to use WPA-PSK instead.
WPA-PSK versions
The Thomson Gateway supports the following WPA-PSK versions:
±
WPA2
(also referred to as WPA2-PSK):
WPA2 is the most secure version, but not all wireless clients already support it. Before you select this
version, make sure all of your wireless clients support it.
±
WPA+WPA2
:
If not all of your wireless clients support WPA2 or you are not sure if they support WPA2, we recommend
you to choose WPA+WPA2. Wireless clients that support WPA2 will use WPA2, the others will use WPA.
±
WPA
:
If none of your wireless clients support WPA2 choose this option.
Which encryption method should I use?
We strongly recommend you to use
WPA+WPA2
.
Although the Thomson Gateway allows you to use WEP or no security, it is not recommended to use these
settings. Only use WEP if you have wireless clients that don’t support a higher encryption level.
Configuring the wireless encryption
Proceed as follows:
1
Open the
Thomson Gateway GUI
.
2
On the left menu, click
Home Network
.
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.
- or -
±
Install the following update:
