This question is asked to me many times, so here is the answer to configure adsl router regarding NTC's ISP. As xDSL service providers don't send door to door personnel as other cable/wireless ISPs, the user has to be self aware and here I have written every thing you need to know about ADSL making you a Guru in no time.

First thing you need to do is buy an adsl router which you can easily get in any hardware shop, preferably digicom, tplink, dlink, billion, planet, etc. It usually comes with a "splitter" whose task is very important. If you plan on using it alone then buy a single port router else if you want to share it with nearby friends then buy multiport router and few meters of cat-5 cables to expand the lan. Though multiport router costs little more but better buy this as may come handy in future. Also if you have laptop or iPhone then better buy wireless router.

Installation Procedures

  • Disconnect your telephone line from distribution point inside your house
  • Connect it to the input of splitter
  • Connect DSL modem in the splitter interface marked 'modem' with R-J11 connecter
  • Connect your telephone set in the splitter interface marked 'phone'
  • The computers are connected with RJ 45 or USB interface to connect to the DSL Modem.
  • Then create the PPPoE Dial Up connection.
  • Because ADSL can be used for broadband access and involves a wide range of multimedia services, you are recommended use a computer with such configurations :

    • Shall be equipped with the 10M/100M Ethernet adapter or USB 1.1. or higher interface
    • Shall support the TCP/IP protocol.
    • CPU above Pentium III, 128 M memory, 10 G hard disk, graphic accelerating adapter with above 2 M displays memory, audio adapter and sound box.
    • Operating systems can be Windows 98SE, Windows Me, Windows 2000 or Windows XP. For system configuration in the WEB interface, the browser of Internet Explorer V 6.0 or later.

  • If you need extensions, connect it after splitter only. (Important!)

So, basically you have to split your main PSTN line into two via splitter using one outlet for router and one for normal phone line use as shown in above figure.

Now bring your phone set and check if both outlets from splitter give dial tone or not. If not then maintain the phone line and recheck the connection.

Attention (Very Important):
Check if your ADSL line is working, the ADSL led will first blink and then glow continuously after you connect your Modem/CPE to the phone line.

If not then either there is no dial tone or your adsl service hasn't been started.

If there is no response showing (no continuous glow) in the ADSL Led of your Modem/CPE, Please contact the corresponding NT MDF (local exchange) to query if there is any problem in your ADSL line.

ADSL Modem (CPE) Configuration
After Purchasing CPE (ADSL 2+ modem), Client are requested go through its manual thoroughly.

Browse the web management page of your ADSL modem. For example if your modem management interface IP Address is

Enter in your web browser.

Provide admin username and password of your modem.

Normal Router IP's are,,,,, etc.
Normal username and password are :
username: admin
password: admin
username: admin
password: password

(Note: customers are exteremly encouraged to go through their Modem/CPE manual to get information like IP address, Admin username and Password).

If you have problem with your ADSL login username and password, contact Internet Section, phone : 5545875,5545876

If you are using modem management interface for the first time then you may be shown quick setup wizard for configuring xdsl.Generally, Modem/CPE can be used in Routing Mode or Bridge Mode.

1. Routing Mode
In this mode, modem/cpe dials with username and password provided by NT. You have to explicitly provide username and password to your modem configuration. In this mode same Modem/CPE can be used to share internet connection to multiple computers.

So in this mode, when you turn on the router, you are automatically connected to the internet whether the computer is on/off. Use this mode if you are sharing the net. Note here username and password refers to adsl234 (not admin as previous) provided by NT.

Configuration Parameters for Routing Mode

VPI --- 8
VCI --- 81
encapsulation --- PPPOE/LLC
Authentication --- Auto

Username --- Provided by NT (eg. adsl1234)
Password --- Provided by NT (eg. adsl1234)
Providing these information should establish connection between CPE and DSLAM

Rx/Tx counters should start to increase

After this you need to save/restart the router. Usually there's the option to save and reboot in the modem web interface (search it) and the restart takes about two minutes.

Note : One does not need to create a dial up or dail while using routing mode. Modem will dial itself. In authentication mode, previously NT used CHAP mode but now they have switched to PAP mode. So, you can provide PAP instead of auto also.

2. Bridge Mode

In this mode your computer dials with username and password provided by NT. This mode is mainly used to connect internet for a single computer.

Configuration Parameters for Bridge Mode

Select Bridge Mode
Encapsulation --- LLC
VPI --- 8
VCI --- 81
Authentication --- Auto

After this you need to save/restart the router. Usually there's the option to save and reboot in the modem web interface (search it) and the restart takes about two minutes.

This is like traditional 56-k dial-up also called Dial-On-Demand. For this you need to create a Dial-up Connection for ADSL(Broadband) as below:

Configuration For XP

  • Go to network connection wizard window
  • Choose Make Internet dialup connection
  • Choose manual option
  • Choose xdsl PPPoe service
  • Provide service name
  • Username - provided by NT (eg. adsl1234)
  • Password - provided by NT (eg. adsl1234)

  • For convenience place a shortcut of this connection in desktop (right click on dial-up and send to desktop). Now dial with the account created

    You are now surfing NT High Speed Internet

    For windows 2000 and Windows 98,


    So, your internet is not working. See if the tips below help:

    1. Internet Protocol properties:

    Go to start-> My Network Places, click view Network connections, right click local area connection and select properties. Set Obtain IP address automatically and Obtain DNS server address automatically option in Internet protocol properties of LAN connection

    Sometimes when you set your TCP/IP Properties to automatic, the ethernet card (lan card) of your computer has problems communicating with your router and it cannot assign the ip address and you see a pop-up like limited or no connection. In this case click the ballon and go to support and click on repair. This automatically refreshes the ip and corrects the problem.

    If the problem presists then assign the ip address manually. Go to start-> My Network Places, click view Network connections, right click local area connection and select properties. In Internet protocol properties of LAN connection, set Use the following IP address option and enter the following:

    In default gateway and preferred DNS server set your router IP address and leave alternate DNS server blank. Click OK and your IP address is changed, no restart required. You can set IP's from 192.168.x.x where x ranges from 0-255 except the used IP's such as router and your lan friend's IP.

    2. UPnP Devices::

    For this first check internet connection by going to start->My Network Places, on the top right pane called Network tasks click the last option called Show icons for networked UPnP devices. Click yes on the dialogue box and now the windows component install takes place. After completion you will see ADSL Router icon when connected. If there's no connection between your computer and router then this device may not show.

    Now go to view network connections, there's also one extra item besides local area connection named internet connection. When connected it'll show as connected and when not disconnected it'll show as disconnected. To make it easier right click internet connection properties and select Show icon in notification area when connected. This will add icon on taskbar which notifies you of internet connection.

    3. Ping :

    Alternatively, you can see if there's net or not by starting command prompt (start->run->cmd) and typing ping If there's ping reply then there's net else the request time outs then there's no net.

    4. Default Gateway:

    Go to your Modem/CPE web interface (eg., enter username (admin) and password for router, you are generally presented with router status something like below:

    Device Info
    Board ID: 96338E
    Software Version: 3.10L.02.A2pB022g.d20h
    Bootloader (CFE) Version: 1.0.37-10.3

    This information reflects the current status of your DSL connection.

    Line Rate - Upstream (Kbps):509
    Line Rate - Downstream (Kbps):1021
    LAN IP Address:
    Default Gateway:
    Primary DNS Server:
    Secondary DNS Server:

    Main thing to notice here is the Default Gateway. If the Default Gateway is blank or Primary and Secondary DNS Server shows then you should know there's no net connection.

    Sometimes the Modem/CPE just needs a reboot/restart to work. Usually there's the option to save and reboot in the modem web interface (search it) or you can turn off and on the router and the restart takes about two minutes.

    Still there's no internet connection while the pulse (dsl or link or data) is continuously glowing then reset the router to default setting through modem web interface or manually reset by pinning a pointed object at the back of the router which has a switch in a hole called reset. Again configure the router and restart. If this doesn't solve the problem then call the following NT numbers:

    Complain and Maintenance Numbers:

    ADSL Maintainance 4231000
    ADSL Voice Direction 1618014244400
    *NT Call Center 197
    *Call 197 to ask for your NT MDF (local exchange) phone no. and contact them.
