Basic Configuration

Make sure your broadband account has been activated and that you have your broadband username and password. You can find these in your welcome e-mail or online in the DSL portal.

Plug one of the microfilters into your telephone socket. You'll need one microfilter for each device that uses your telephone line (Sky, fax, additional handsets).

Plug the grey broadband cable into the microfilter socket marked DSL.

Plug the other end of the cable into the DSL socket on the back of the router.

Connect the power adapter and switch the router on with the power button at the back.

The power light will initially be red and the Broadband light will flash. Wait until they stop flashing and turn green before moving on to the next section.

  3. DSL Socket

Plug the yellow Ethernet cable into one of the 4 available Ethernet ports on the back of your router.

Plug the other end of the Ethernet cable into your computer's Ethernet port.

Your computer is now connected to the network.

1. On your computer, open a web browser. You’ll be taken straight to the router’s welcome page.

Click Set up my Thomson Gateway to begin.

The Easy Setup wizard will open in a new window. Click Next

On the Service Selection screen, make sure that Data (Default) is selected, then click Next.

Only choose Data (Custom) if you want to use No-NAT or other advanced setup options.

On the Router Internet Connection screen, make sure that VPI/VCI is set to 0.38 and that Connection Type is set to PPPoA (UK Default).

Type in your Broadband Username and Password and click Next.

Now choose the type of wireless security you want to use. We recommend leaving this as WPA-PSK - it's the most secure method. Click Next.

Next choose a Username and Password, this is to stop unauthorised access to your router settings.

You should change these to something that's easy to remember as you'll need to enter them every time you want to check or change your router settings.

When you've made your choice click Next.

If you don't change the username, it'll be set to Administrator (note the uppercase A).

The password will be the serial number of your router, which you'll find on the bottom.

Ignore the part in brackets, the bit you'd need in this example is CP0752SFB4J (note the uppercase CP).

Finally you’ll see a summary page, make sure everything is correct and press Start.

The router will restart, and ask you for login details.

Enter these and press OK.

When the wizard finishes you’ll see a confirmation screen, click Finish.

If you have any problems with your router, you can return everything to the default settings by using the reset button.

Make sure you have note of your broadband username and password before you start Use a paperclip, pen or pointed object to press into the reset pin hole on the back of the router. Keep the button pressed in for at least 7 seconds. When the power light goes red, release the button and wait until the power light turns green again.
