Setup of TP-Link TD W8970.

This article is for a novice who is venturing into modem/router set-ups for the first time. 

Connecting the Modem Router: See Fig 1.

1)  Connect the ADSL Line.

Use a separate external splitter which can divide the data and voice, and then you can access the Internet and make calls at the same time. The external splitter has three ports:

• LINE. To connect to the wall jack

• PHONE. To connect to the phone set.

• MODEM. To connect to the ADSL port of the modem.

1) Plug one end of the ADSL cable into the ADSL port on the rear panel of the unit. Connect the other end to the MODEM port of the external splitter.

2)  Connect the Ethernet cable. Attach one end of a network cable to your computer’s Ethernet port or a regular hub/switch port, and the other end to the LAN port on the modem router.

3)  Attach the power adapter. Connect the power adapter to the power connector on the rear of the unit and plug in the adapter to a electrical point. Switch on the unit.

4)  Power on the computer and LAN devices.

Next step is to configure your computers IP address. (For Win 7)

Click on the Start button ->Control Panel -> Network & Sharing centre. Click on ‘Change Adapter Settings’ (In the left Panel)

Right click on Local Area Connection ->Properties -> Double click on ‘Internet Protocol Version 4’ -> In the General Tab, Select ‘Obtain an IP automatically’  then select ‘Use the following DNS Addresses’ & you are free to use any DNS address eg: Open DNS, Google DNS, Comodo DNS, Google DNS.

You can run the Ping command in the command prompt to verify the network connection.

Please click the ‘Start’ button on your desktop, in the search field type ‘run’ & in that window type ‘ping’, and then press ‘Enter’.

If the result displayed is similar to the screen below, the connection between your PC and the modem router has been established.

If in the same screen you get a display of ‘Timed Out’ it means that you’re PC has not connected to the unit.

Now for setting up this model.

The Web-based utility can be used on any Windows, Macintosh or UNIX OS with a Web browser, such as Microsoft Internet Explorer, Mozilla Firefox or Apple Safari. My setup is in the Windows environment & using Mozilla Firefox.

1)    Open Firefox & type in the address bar & pres ‘Enter’ Fig.5 (Below)

2)    A login window will appear, as seen below. Enter ‘admin’ for the User Name and Password, both in lower case letters. Then click the ‘OK’ button or press the Enter key.

If the above screen does not pop up, it means that your Web-browser has been set to a proxy. Go to Start -> Control Panel -> Network & Sharing Center→Internet Options→Connections→LAN Settings, in the screen that appears, cancel the Using Proxy checkbox, and click OK to finish it.

3)    After successful login we will see the eighteen main menus (Fig 6a See below) on the left of the Web-based utility. On the right, there are the corresponding explanations and instructions.
