3.1Configuring The THOMSON TG185n As Access Point
Procedure
Before you can use your THOMSON TG185n as wireless access point you have to complete following steps:
1Switch the THOMSON TG185n to access point mode.
2Assign a static IP address to your computer.
3Configure the wireless settings of your THOMSON TG185n.
4Configure the IP settings of your THOMSON TG185n (optional).
5Connect your THOMSON TG185n to your Internet gateway.

7Configure your computer to obtain an IP address automatically.
Switch the THOMSON TG185n to access point mode
Proceed as follows:
1On the back panel of your THOMSON TG185n, move the switch to the access point position.
s Point
2After a few seconds the Access Point LED will turn green.
Assign a static IP address to your computer
The IP address must be between 192.168.1.14 and 192.168.1.63 (for example 192.168.1.20). The subnet mask
must be 255.255.255.0.
For more information, see “7.1 Assigning a Static IP to Your Computer” on page 44.
Configure the wireless settings of your THOMSON TG185n
Proceed as follows:
1Open your web browser and browse to http://192.168.1.11
2The THOMSON TG185n Web Interface appears. On the Basic Setting menu, click Wireless Setting.
3The Wireless Settings page appears.

5In the Select Security Policy list, select the security policy of your choice and enter a passphrase/
encryption key. For more information, see “3.4 Securing Your Wireless Network” on page 16.
If the Enable WPS (Wi-Fi Protected Setup) check box is enabled you can only select the
following policies:
None
WPA-PSK
WPA2-PSK
WPA-PSK-AUTO
If you want to select another policy (not recommended), clear the Enable WPS (Wi-Fi Protected
Setup) check box.
For more information on WPS, see “3.2 Connecting a Wireless Client via WPS”.
6Select the WPS Configured check box, this way you are sure that your settings will not be changes during
WPS.
7Click Apply.
8The THOMSON TG185n prompts you that the configuration was successful.
Configure the IP settings of your THOMSON TG185n (optional)
If you still want to be able to access your THOMSON TG185n after connecting it to your Internet gateway, you
have to make sure that they are both using the same IP range.
If your Internet gateway is also a THOMSON product, this will automatically be the case and no
extra configuration is needed. Continue with the next topic.
If you choose not to do this configuration or you don’t know the IP settings of your Internet gateway, yo u will
only be able to access the THOMSON TG185n by assigning a static IP address to your computer that is the
same range as your THOMSON TG185n.
To change the IP settings of your THOMSON TG185n:
1On the Basic Setting menu, click Device IP Setting.
2The Device IP Setting page appears. On this page you can configure the IP address of your THOMSON
TG185n. Select:
Assign static IP address to this device if you want to choose the IP address for your THOMSON
TG185n yourself.
Use the DHCP client protocol to automatically get the IP address for this device if you want your
Internet gateway to assign an IP address to your THOMSON TG185n. In this case you do not have to
provide an IP address, IP Subnet Mask and Gateway IP Address.
3In the IP address box, type an IP address that is in the same range as your Internet gateway.
4In the IP Subnet Mask, type the same subnet mask as your Internet gateway.
5In the Gateway IP Address, type the type the IP address of your Internet gateway.
6Write down this IP address and subnet mask. From now on, you can only access the THOMSON TG185n
at this address
Connect your THOMSON TG185n to your Internet gateway
Proceed as follows:
1Disconnect the Ethernet cable from your computer.
2Plug the Ethernet in an Ethernet port on your Internet gateway.
3Your THOMSON TG185n is now connected your Internet gateway via the Ethernet cable.

3.4Securing Your Wireless Network
Introduction
By using encryption, communication between the wireless clients and your THOMSON TG185n 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:
For Enterprise environment:
WPA(2) Encryption:
To use this encryption, a RADIUS authentication server must be available in your network. In this scenario
wireless clients first have to authenticate to the RADIUS server. The RADIUS server will tell the wireless
client which key it should use to encrypt its data. The RADIUS server will change this key after a specified
time.
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(2)-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 TG185n.
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.
s Point
Which encryption method should I use?
We strongly recommend you to use the highest level of encryption that is supported by all your wireless
clients.
Configuring the wireless encryption
Proceed as follows:
1Open your web browser and browse to http://192.168.1.11
2The THOMSON TG185n Web Interface appears. On the Basic Setting menu, click Wireless Setting.
3The Wireless Setting page appears.
4In the Security Policy list, you can select the policy of your choice. If you want to use:
WPA(2)-PSK Encryption, continue with “3.4.1 Configuring WPA(2)-PSK Encryption” on page 17.
WEP Encryption, continue with “3.4.3 Configuring WEP Encryption” on page 19.
WPA(2) Encryption, continue with “3.4.2 Configuring WPA Encryption” on page 18.

3.4.1Configuring WPA(2)-PSK Encryption
Procedure
Continuing from “ Configuring the wireless encryption”:
1In the Select Security list, select:
WPA2-PSK:
WPA2-PSK is the most secure version, but not all wireless clients already support it. Before you select
this version, make sure that all of your wireless clients support it.
WPA-PSK-AUTO:
If not all of your wireless clients support WPA2-PSK or you are not sure if they support WPA2-PSK, we
recommend you to choose WPA-PSK-AUTO. Wireless clients that support WPA2-PSK will use WPA2-
PSK, the others will use WPA-PSK.
WPA-PSK:
If none of your wireless clients support WPA2-PSK choose this option.
To use WPA2-PSK on Windows XP Service Pack 2 (SP2) you first have to install Wi-Fi Protected
Access 2 (WPA2)/Wireless Provisioning Services Information Element (WPS IE) update or install
SP3 on your Windows XP.
You can find the WPS IE update on http://support.microsoft.com/kb/917021
2In the Pre-Shared Key box, type a pass phrase (also known as Pre-shared key) of your choice. The key
must consist of 8 to 63 alphanumeric characters or 64 hexadecimal characters (characters from 0 to 9 and
from A to F).
3Click Apply.
4The THOMSON TG185n prompts you that the configuration was successful.
5Configure your wireless client(s) with the same settings.

3In the Server IP address box, type the IP address of your RADIUS server.
4In the Port Number box, type the RADIUS Port.
5In the Shared Secret box, type the RADIUS Key.
Enable WPA
Proceed as follows:
1On the Basic Setting menu, click Wireless Setting.
2Clear the Enable WPS (Wi-Fi Protected Setup) check box.
3In the Select Security Policy list, click the desired WPA version.
WPA2:
WPA2 is the most secure version, but not all wireless clients already support it. Before you select this
version, make sure that all of your wireless clients support it.
WPA-AUTO:
If not all of your wireless clients support WPA2 or if you are not sure if they support WPA2, we
recommend you to choose WPA-AUTO. 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.
To use WPA2-PSK on Windows XP Service Pack 2 (SP2) you first have to install Wi-Fi Protected
Access 2 (WPA2)/Wireless Provisioning Services Information Element (WPS IE) update or install
SP3 on your Windows XP.
You can find the WPS IE update on http://support.microsoft.com/kb/917021
