1. Before you begin

This guide will take you through setting up your Thomson 585v7 Wireless router from scratch and applies to both Windows and Apple OS X systems.

Make sure your broadband connection is up and running before you set up your router - we'll email you when it's ready.

You'll also find a quick install guide and a sticker showing your wireless security details.


2. Connecting Microfilters & Cables


Microfilters look small and unimportant but they’re essential for keeping your phone and Internet services from interfering with each other. Without microfilters you'll see poor speeds and connection drops

  • Plug a microfilter into each telephone socket that's used at your property
  • If you had to unplug something you can plug it back into the Phone socket of the microfilter
  • If you need more filters, you can order them from us or buy them from most electrical or computer stores
  • See our Guide To Fitting Microfilters if you need more help with this


  • Plug the grey broadband cable into the microfilter socket marked ADSL
  • Plug the other end of the cable into the DSL socket on the back of the router
  • If you've received a 2-part power supply (as in the picture above), clip the pins onto the adapter
  • Connect the power supply and switch the router on with the power button at the back

The Power light will turn red at first and the Broadband light will flash - wait until they've turned green (and stopped flashing) before continuing.


3. Connecting to your Computer

Now it's time to connect the router to your computer.

You can use either Wireless or Ethernet. Choose one of these and follow the steps below.


If you're using a Thomson TG123g Wireless Adapter to connect to your wireless network, follow the guide linked below:

If you're using your Mac's built in wireless facility:

  1. Click the Wireless Icon on your taskbar
  2. Find PlusnetWireless on the list and connect to it
  3. You'll be asked to enter the wireless security key. Use the WPA PSK key shown on the bottom of the router, it's 10 characters long and the letters are CAPITALISED
  4. Your computer is now connected to the network. Move onto the next section, Connecting to the Internet


  1. Plug the yellow Ethernet cable into one of the 4 available Ethernet sockets on the back of your router
  2. Plug the other end of the Ethernet cable into your computer's Ethernet socket
  3. Your computer is now connected to the network. Move onto the next section, Connecting to the Internet


4. Connecting to the Internet

During the following steps you may be asked for router login details, see What are the router username & password? if you're not sure what these are.

  1. On your computer, open a Web Browser, such as Internet Explorer or Safari. You'll see The Thomson welcome page. (If this doesn't happen, or you get an error page, see No Welcome Page?).

    Click Set up my Thomson Gateway and go to step 2.

    The Thomson Gateway Welcome Page, click Setup My Thomson Gateway.
  2. The Easy Setup wizard will open in a new window. Click Next.

    Click Next to begin the Easy Setup Wizard.
  3. On the Service Selection screen, choose Plusnet and click Next. Only choose Other if you want to use No-NAT or other advanced setup options.

    If you see different options on this screen, please follow the guide for 585v7 routers ordered and received before 27th November 2008.

    Choose Plusnet from the Service list and click Next.
  4. Enter your Broadband Username and Password and click Next.

    • Find your Broadband Username under the summary section of My Account.
    • The Password is the one that you use to log in to this website.
    Enter your Broadband Username & Password and click Next.
  5. Finally you'll see a summary screen. Have a quick check through the settings to make sure everything is correct. Use the Back button if there's anything you need to change. Press Start to finish the setup wizard and connect to broadband.

    Check the settings are correct and click Start.

    After about a minute the Internet light on the router will go green and you'll see a confirmation screen. Click Finish.

    That's it! You're connected to Broadband.


5. Troubleshooting

No welcome page?

If you see an error page during step 1 of Connecting to the Internet, type into the address bar and press enter on your keyboard.

You'll be taken to the Thomson home page. Click Thomson on the left menu. Next click Set Up (under Pick a Task... at the bottom of the page) and go back to step 2 to continue configuring your router.

What are the router username & password?

If you've not changed or added a password then the details you'll need to use depend on when you received your kit:

  • 27th November - 3rd Dec 2008

    Username: Administrator Password: Serial Number

  • 3rd Dec 2008 - 23rd Nov 2009

    Username: Administrator Password: No Password

  • 24th Nov 2009 onwards

    Username: admin Password: Serial Number

All details are Case Sensitive

The Serial Number is shown on the bottom of the Thomson Gateway:

This is the Serial number sticker on the bottom of your router.

Resetting your router

If you have any problems setting up your Thomson Gateway, you can reset it and start again.

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.

You now need to apply your settings again. Follow this guide again from Connecting to the Internet.
