How to access the router

Using a browser of your choice (such as Internet Explorer, Mozilla Firefox, Google Chrome or Safari), enter the IP address of the router into the address bar. If you received the router from Demon, the address by default should be

If you are unsure what your IP address is, go to Start and click on Run, then type in cmd and click on OK. You should now have a black window on your screen with a flashing cursor. Now type in ipconfig and press enter.

Please note: In Windows 7 and above, the run button is not always present, but a command prompt can be accessed by going to Start > All Programs > Accessories > Command Prompt.

You should now see a list of IP Addresses, for example:


Windows IP Configuration

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix: lan
IPv4 Address:
Subnet Mask:
Default Gateway:

The IPv4 Address (which may just be listed as IP Address depending on your network card) is the address of your computer, and the Default Gateway is the address of the router.

Once you have entered the IP address of the router into the address bar of your web browser, you should see a login prompt asking you for the username and password to get into the router.

The login details for the Demon supplied Technicolor routers are:

Username: admin
Password: DemonCPE

Enter these login details and click OK. You will now be logged into the router and the homepage will be displayed:

How to check or change the ADSL login details

Once you’re logged into the router, click on Home (if you are not already on the Home screen), then click the Internet link near the middle of the page under the Broadband Connection heading.

Please note: If you have accessed this page while the router is connected to the internet, you will have to click on the Disconnect button before it will allow you to make any changes to the username and password.

When you’re happy with the login details you have entered, click on the Connect button. Once connected, it will redirect you to a status page showing you how long you have been connected, how much data you have transferred, your internet IP Address and some other useful information.

Checking your Line Stats/Sync Information

Once you’re logged into the router, click on Broadband Connection on the left side of the page.

In the main part of your screen, you should now have two main headers – DSL connection and Internet. Underneath DSL connection, click View more…

This will take you onto another screen showing your current line/sync status.

If your line is ‘out of sync’, you will see the following message:

Ensure that the router is connected and filtered correctly to your telephone line. If you need help in doing this, please read our ADSL Broadband setup guide.

To view more details such as Line Attenuation, SNR Margins and Errors, click on Details in the top right hand corner.

When you first receive a wireless router from Demon, the Network Name (SSID) and Wireless Key (password) will match the sticker on the underside of the router, but you have the option to change this.

To make changes to the wireless, click on the Home Network menu on the left.

In the main part of the screen, you should now see a simple diagram of the network with Wireless at the top and Ethernet just below it.

Within the Wireless part of the diagram click on WLAN: TNCAP###### (TNCAP###### being the SSID or Service Set Identifier).

You should now be able to see some basic information about the wireless connection.

To view the wireless password or to make changes to the wireless settings, click on the Configure link in the top right hand corner.

On this page, you will be able to make the following changes to the wireless settings on the router:

Setting What it does
Interface Enabled Turns the wireless on and off (if the box is ticked, the wireless is on).
Power Reduction Enabled When this setting is enabled, the access point is switched off and is only powered on periodically to be able to detect new clients. If new clients are detected the wireless access point is fully powered again. This is only possible if there are no devices connected to the router.Please note: Enabling power reduction may have an impact on the reliability of your wireless connection. This feature is intended for advanced users only.
Network Name (SSID) This is what your router name is displayed as when you search for available networks.
Interface Type Unless you have certain devices trying to connect to the wireless network you shouldn’t need to change this, but you have the option of the following:

  • 802.11b
  • 802.11g
  • 802.11n
Channel Selection This allows you to choose what Channel your router broadcasts on.If you leave it set to Automatic the router will choose a channel for you. Choosing Manual will give you the option to set the channel between 1 and 13.By default this should be set to Automatic.
Allow multicast from Broadband Network Gives you the option to block or allow multicast broadcasts over the network.
Broadcast Network Name This allows you to prevent other devices from seeing your wireless connection when they scan for available networks.By default the router is set to broadcast the network name (SSID).
Allow New Devices Choose how you want new devices to connect to the wireless network.
Encryption Choose the type of security you wish to use for devices connecting to the network:

  • Disabled
  • WEP

If you set it to Disabled this will allow anyone to connect to the wireless network without a password. WEP is a somewhat out-dated technology and can be easily cracked. Using WPA will allow you to set an alphanumeric password between 8 and 63 characters long.

WPA-PSK / WEP Encryption Key This is where you set the password for the wireless network.
WPA-PSK / WEP Version This will allow you to set the level of encryption to be used:

  • WPA2
  • WPA + WPA2
  • WPA

WPA2 is the latest and most secure version but not all devices currently support it.

By default this should be set to WPA + WPA2 which will allow devices to use either WPA or WPA2. It’s best not to change this setting unless you’re confident that all your devices support WPA2.

Once you’re happy that all the settings are set correctly, click on Apply to save the changes.

Game and Application Sharing (Port Forwarding)

This is where you can create port forwarding rules and control UPnP.

To get to Game & Application Sharing, click on the Toolbox menu on the left hand side.

Next, either click on Game & Application Sharing below Toolbox on the left hand side or click on the icon in the main section in the middle.

You can create, modify and assign entries under Pick a task…. When you create port forwarding rules, you are given the option to either clone an existing rule or manually enter your port maps.

Any assigned port forwarding rules will be displayed near the bottom of the page in a table under ‘Assigned Games & Applications’.

Event Logs

You can use the event logs to help you diagnose issues you may be having with your broadband service. For example, if you’re finding that the connection is intermittent, you can use the Event Logs to determine if the router is losing sync or just authentication.

To get to the Event Logs, click on the Technicolor Gateway link on the left hand side of the screen and then click on Event Logs on the sub menu now visible.

The Category list allows you to filter the events shown in the Recorded Events table. For example, by selecting Connections from the drop down menu, you can view all connection-related events, so you’ll only see events such as the router syncing to the exchange or logging into the ISP’s network.

The Recorded Events table gives you an overview of the last event logs that have been recorded since the router was turned on.

The first column of the table indicates the importance of the event log.

Indicator Description

We have listed just a few events that will help you diagnose any issues you may be experiencing with your broadband service.

Event What it means
Warm Restart The router has been rebooted, either using a command line or through the interface.
Cold Restart The router has been rebooted physically by switching it off and on.
xDSL linestate down The router is out of or has lost sync.
xDSL linestate up The router has gained sync. This will usually be followed by the sync speed and other line stats.
WIRELESS Interface turned on The wireless has been enabled.
PPP Link Up The router has connected to the ISP’s network.
PPP Link Down The router has lost authentication with the ISP’s network
