Seting up TP-Link TD-W8968

Recently I had an opportunity to setup TP-Link TD-W8968 which is a ADSL modem cum WiFi router. This article is for a novice who is venturing into modem/router set-ups for the first time.This post is for MTNL/BSNL on ADSL+  connections.

Connecting the Modem Router: See Fig 1.
1)  Connect the ADSL Line.
You can use a separate splitter. External splitter 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: Connect to the wall jack
• PHONE: Connect to the phone sets
• MODEM: Connect to the ADSL port of  the modem.
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)
Fig. 2

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 addresses eg: Open DNS, Google DNS Comodo DNS.
Open DNS & & &
or Google DNS &
Comodo DNS. &
Fig. 3

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.
Fig. 4

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 fifteen main menus (See below) on the left of the Web-based utility. On the right, there are the corresponding explanations and instructions.  

4)    If we click on ‘Status’ we shall see the fig as seen below in Fig 7. below

5)    We click on ‘Quick Setup’. Here the modem router supports three modes: ADSL Modem Router Mode, 3G Router Mode and Wireless Router Mode. Choose your desired mode and then click Next. See Fig 8 below.

ADSL Modem Router Mode: In this mode, the device enables multi-users to share Internet via ADSL using its ADSL port and share it via wireless at 300Mbps wireless 802.11n speeds. 
3G Router Mode: In this mode, the device allows multi-users to share a 3G mobile broadband connection via wired or wireless connection.
Wireless Router Mode: In this mode, the device enables multi-users to share Internet via Ethernet WAN (EWAN) using its interchangeable LAN/WAN port and share it via wireless at 300Mbps wireless 802.11n speeds. 
6)    We select ‘ADSL Modem Router Mode’. Change the VPI = 0 & VCI = 32 for MTNL Mumbai (these values which are used to define a unique path for your connection). Click 'Next'.
Fig 9.

These VCI & VPI I have mentioned above is basically for MTNL for the other ISP’s in India.
Connection Name

We then come to the Fig 10. as seen below

1)    Here we select PPPoE & then click ‘Next’. After that.
2)    We come to the ‘PPPoE’ window and we come to the Fig 11 as seen below.

3)    The ‘Username’ is one’s telephone number. ‘Password’ is the CA number given on one’s tel bill enter password again & click ‘Next’.
7)    Here we come to the 3G window (3G backup function is disabled by default.). Click Next to skip to the next step

Wow Wow Wow !!!!
You should be hired by the manufacturer to write their installation instructions.

socrates said...

Have you succeeded in setting up IP6 for your ISP & is it working? If so can you post it at the TP-Link India forum

Fabian Tellis said...

Hi Socrates,

Very comprehensive and helpful. It helped me so very much. It is really required as the company installation guide manual does not give so much in detail and it skipped quite a few important things.

Hi Socrates,
great job my friend. What an excellent way of informing how to set up. Great job.
Thanks again very much.

Hi, this is a great work writing to connect for the wan part.

do you know how to connect to 3g alone without WAN or DSL.

hello! may i ask how do you set this up with an etisalat al shamil internet connection the one that uses a "PPPOE" injector modem

thanks so much!!!!!

socrates said...

This post is basically for MTNL/BSNL on ADSL+ connections. Sorry I don’t have any experience in any other.

Abhinav Saxena said...

Hi Socrates.
I am using this modem for sometime now. With your extensive explanation, I could set up the modem without any difficulty.
Now I realise that I can only connect max 7 wifi devices. I tried to find but am unable to find the setting to increase the number of wifi devices simultaneously connected. Can you please help?
Thanks anyway for all the help so far.

socrates said...

It’s very strange as I connect many more than that & I don’t have any trouble. Are you using DHCP (I am ), just check you have not made any changes there. Start IP is & End IP is
Also if you are using MAC filters, I hope you have added the MAC addresses of ALL devices.
If this does not sort out your problem then I suggest a factory reset & start from scratch. If that does not sort out the problem then I think you should contact the distributor & exchange it, if it’s in warranty.

Hi bro
Can u pls help me on this Recently I have bought tplink TD8968 version 4 my MTNL BROADBAND.after instalation specialy going thru your instructions for set up the was good the Internet is working. But just that there are frequent drop offs or disconnections.I am not a computer software wiz so please give some settings for fine tuning and specially to fix the problem of constant disconnections. Pls help

2677d said...

Pls reply to my problem coz MTNL aunties don't care a DAMN .the user interface of version 3 and version 4 is so very different have tried a lot but in vain.

socrates said...

My post is for the ver 3 but the fundas will be the same even if the screenshots are different. Check your ‘attenuation’ & ‘SNR’. SNR < 10 will give you DC. Disconnections usually means poor line quality which has to be rectified by the linesman. Remember that your tel line should come to your modem (via splitter) first then to your phone instrument else you can have DC everytime the phone rings or is picked up. When you make a complaint just say your are getting many disconnections (DC)

2677d said...

Thanks for your reply will get back to you ....if the problem remains.

socrates said...

@2677d Were you making any changes in your modem? What do you mean by ‘cannot access the internet’ what type of error are you getting. Are you referring that you cannot access any site? If yes then check what your MTU is. Change it to 1492. If that does not work then reset & setup your modem again. Hope this helps
