How to Configure a BSNL Broadband Modem Manually?

BSNL is one of the most popular Internet Service Providers in India. They provide different models of DSL modems to their customers. Some of the popular BSNL modems are from D-Link, Teracom, Netgear, etc...

Though they supply different modem models, the procedure to configure them is very similar.

Let me explain the procedure to configure a DSL modem with your BSNL broadband connection with an example. Let me pick a Teracom modem to explain the setup procedure.

To configure BSNL Broadband Internet on the Teracom modem, we don't need to run the setup CD. We can manually set up a broadband Internet connection on a Teracom modem if you have the Internet Username and Password provided by BSNL.

In the manual configuration, we should log in to the Teracom modem by typing the modem username and Password(Teracom username and password are not the same BSNL Internet account username and password ). Since BSNL is a DSL broadband ISP, we need to configure the Teracom device in PPPoE mode.

BSNL Modem in Bridge Mode Vs PPPoE Mode

In PPPoE mode, we can connect more computers to the modem and share the Internet. If we configure it in bridge mode, only one computer can access the Internet.

Configure Internet Connection on BSNL Modem

  1. Login

    Type on the browser address bar and press enter to access the modem login page. You need to enter the Teracom modem username and password to access the BSNL modem.
    Bridging BSNL gateway

    Default BSNL modem username and password are:

    User Name: admin
    Password: admin

    Click OK. Now you will be on the modem configuration page. If you forgot the password, you need to reset the modem.
    full speed

  2. Click on Configuration Tab

    Now click on the Internet Connection to configure Internet on the BSNL Teracom modem.
    Change Connection type

  3. Remove old connections

    You can see several pre-configured connections on this page. You should delete all of them by pressing the delete button.

  4. Add a new connection.

    Now click on the add button at the bottom of the page to create a new connection.

    Now add the following parameters:

    PVC Name: PVC0

    VPI : 0
    VCI: 35

    Service Category: UBR with PCR

    Keep all other default information and click Next.

  5. Select BSNL Connection Type

    Now select PPP Over Ethernet (PPPoE) and LLC/ SNAP.
    LLC value

    Now click Next.

  6. Configure WAN IP Settings

    Select the option Obtain IP Automatically. Make sure to check the checkboxes NAT and Default Route.

    Click Next.

  7. Set Username and Password

    Type the username and password provided by BSNL. You can enter the service name as BSNL Internet.

    Teracom username

    Press the Next button to reach the summary page.

    Click on Apply.

  8. Reboot BSNL Modem

    Click on the Admin tab and then click on the Reboot.

    From the drop-down menu, select Last and click on Reboot. Now, wait 1 minute to let the modem reboot. After this, close the window and check your Internet connection.

    We have successfully configured the Internet connection on the Teracom modem.

As we know, this modem supports the wireless feature. To configure wireless, click on the link below.

  2. Click on Admin

  3. Click on Firmware upgrade.

    Good. That was a nice modem configuration. I think teracom modem is good one from BSNL. After all how can I configure multiple computers in this modem . I have a version of this teracom modem with just one lan port

  2. You can share your Internet connection among multiple computers even if your Teracom model has just one LAN Port. You should configure the Wireless LAN and connect multiple computers.

  29. Where can I download BSNL dataone broadband modem driver? Do you have CD or disk for it? Can you tell me how to install and upgrade this modem driver?

  30. Sooraj11:04 AM

    I have type 2 modem from bsnl dataone. Can I use same steps to configure it? Actually what is the difference between type 1 modem and type 2 modem supplied by BSNL? Yes I have WiFi in my modem.

  31. How many types modem supplied by BSNL ? Is BSNL ADSL connection or Cable Internet connection ? I have a coaxial cable modem, can I connect it with dataone?

  32. hii,
    i m using teracom(type 1) modem provided by bsnl on my desktop. Now i want to use it with my laptop also using USB.
    please provide me step to proceed.

    thank u

  33. Admin1:07 AM

    You cannot use both Ethernet port and USB port of a modem to access Internet at the same time. If you have only one LAN port on your type 1 modem supplied by BSNL, you may have to use either a switch or ICS(Internet Connection Sharing) to share Internet between your PC and Laptop.

  34. My terracom modem supplied by BSNL,Chennai gets internet connectivity through the LAN port using a data cable. However, some glitch has occurred in the wireless settings with the result that I am not able to access internet on my smart phone. I wanted to get on to the config. link to check entries. But every time I try to log onto the config. page using default user name and pwd, they are rejected and a message comes saying it is a protected content. Pl. advise me as to how I can get over this problem and recheck the wireless access settings. Thanks.
    P B Krishnaswamy.

  35. Have you changed the Teracom modem default username and password ? If yes, you must use the current username and password to login modem setup page. If not just clear the browser history and cookies and try to login back.

    The USB port is for the use of connecting your PC to the modem using a USB cable to get Internet in case if you don't use Ethernet cable or WiFi. You cannot connect USB dongle to it.

  63. Have you properly reset the modem ?
    Type ipconfig on command prompt and check the default gateway address.

    Also try hard reset by following the link below.

  64. @Naveen,

    It seems your modem is configured in bridge mode. You must configure the modem in PPPoE. Try follow the guidelines in this article and if it is not working ask the ISP customer support to configure your modem in PPPoE mode.

    1. Hi I contacted customer care but there is no use. .. they don't know abt vci and vpi.. how to find it right for my isp (apptel broadband). What they stand for?

  65. alex george i want to update firmware my teracom modem. how can i download firmware file and how to install.

  66. Hi Arun,

    Once logon to the web based setup page, click on Admin. Under admin, you can see firmware upgrade. Click on it and click the button 'check for updates'. If new version is available, you will be redirected to that page. download it and upload using browse button.

  67. Hi Naveen,

    I have no experience with using apptel broadband and I do not know how to configure their modem. All I can suggest is to send an email to their technical support wing using the email address

    VPI = Virtual Path Identifier

    VCI= Virtual Channel Identifier

    These two are important values which enables connection between Service Provider and modem at customer place.

  68. dear sir,kindly look the matter as we having a modem teracom configured with bsnl conn. for broadband as we are able to surf internet facility only via wire but not working through wireless wifi
    plz reply sir

  69. @Ganderbal Indanegas,

    It seems either the Local Area Network (LAN) is not configured properly. Could you answer the following questions ?

    1. How many devices are connected to the modem via Ethernet cable ?

    2. Are you sure you are connecting the correct Wireless network with correct password

    3. Make sure there is no MAC address filtering is enabled in wireless network.

    4. What is the IPv4 address you are getting while typing ipconfig on the command prompt on the computer which is connected to modem using cable ?

  70. When I connect my BSNL Teracom modem wifi with my mobile it will show "obtaining IP address" and not connected. But If I select static in setting it will ask for IP address and after entering IP address it will connect. Is it possible to not entering any IP address and only entering my wifi password to connect to internet. Please help me.

  71. You must be able to connect to the WiFi automatically after you enter WiFi name (SSID) and password. However, your computer connects to WiFi once you use static IP address and I suggests you to keep the same IP address as long as you are not having any issues to connect.

  72. dear sir, I want to use this modem for some private ISP which uses ethernet cable, I want to use WIFI through this modem cum router, kindly help me!!!
