If you are in India and have a BSNL DataOne broadband internet connection, you might have experienced this problem quite often. Your connection appears to be OK and all lights glowing on the modem. Your LAN icon is also showing connected. However, you are not able to open any website.

This is a common problem faced by BSNL broadband users. The DNS server they use is not that active to respond.

DNS stands for Domain Name Server. When you type www.google.com, the DNS server converts the name into an IP address of Google. Then it follows the IP address to fetch you the webpage.

Now, due to a defective DNS server system, your typed address can not get resolved into IP. So you reach nowhere.

Verify if this is the problem:

Try typing the IP of the website instead of the name. That is, type instead of http://www.google.com and you should reach the Google website.
Some other websites’ IP for easy reference:

If you are able to open the website by typing the IP as mentioned above, then we are sure it was the problem with BSNL’s DNS servers.

How to solve this:

Open your network connection properties. Usually you open it by double clicking on the LAN icon on your system tray, then going to ‘Properties’ and then ‘Internet Protocol (TCP/IP)’ properties.

Now choose to ‘Use the following DNS server addresses’ and enter the two addresses and for OPENDNS.

Change DNS server addresses

Change DNS server addresses

Useful Tip
If OPENDNS doesn’t work, try GOOGLE’S FREE DNS SERVICE: and

Now save and close everything. Your internet should behave normal now.

Upgrade your Hardware

The default router provided/sold by BSNL on new connection isn’t usually the best one for performance; and this might be the reason for intermittent troubles, especially fluctuating wifi signal problems. Consider buying a mid-range wifi router from a reputed brand. Make sure the one you buy has a sufficiently long coverage for all the rooms in your house. Here’re a few you can look at:

The basic one that works great:

A little more expensive and robust:

    • Venkat says:

      I guess it’s not working while using the cable as well?

      Did you try changing DNS settings as mentioned in this guide?

      Also try using a different browser.

      Try deleting browser cookies and temporary files.

      Open command prompt and type “ipconfig /flushdns” without quotes and hit enter. It will clear the DNS cache.

  27. Amit Trivedi says:

    Thanks for your suggestions, but for me neither this OpenDNS is working nor that Google free DNS configuration are working…I don’t know how to tackle this issue. Since here at my place BSNL service is provided, “as it’s available” and no support at all.

  28. Charak says:

    Well, the DNS fix is one major thing you can try whenever BSNL connections are down. especially when some sites open and some others don’t. However, BSNL broadband has a lot of other issues and net goes down due to those. You will have to call them and wait for the mercy of the staff.

  49. Hi

    My problem is that I am not able to access the websites with the ip address as well. Any Suggestions?

  50. Kumar says:

    Hi All,

    My problem was with the below commands. I ran these command in Command prompts.

    netsh int ip show int

    This resulted me the following

    Idx Met MTU State Name
    — ———- ———- ———— —————————
    1 50 4294967295 connected Loopback Pseudo-Interface 1
    10 25 1500 connected Wireless Network Connection
    13 5 1500 disconnected Local Area Connection 2
    18 50 1500 disconnected Bluetooth Network Connection

    I took the Idx number 10 corresponding to wireless connection in the below command.

    netsh interface ipv4 set subinterface “10″ mtu=1430 store=persistent

    To see the changes

    netsh int ip show int

    Idx Met MTU State Name
    — ———- ———- ———— —————————
    1 50 4294967295 connected Loopback Pseudo-Interface 1
    10 25 1430 connected Wireless Network Connection
    13 5 1500 disconnected Local Area Connection 2
    18 50 1500 disconnected Bluetooth Network Connection

    Now all the websites opening for me which are not earlier.


    • Ayyamperumal.R says:

      This worked for me. Great. I use to use tcp/ip optimizer BUT now this simple dos command does the same.
      To set i used:
      set subinterface “12″ mtu=1430 store=persistent

      then to check i used
      set interface /?

      it shows the MTU set for those connections.
      Great DOS command and the credit goes to you ….

      I hooked up my new router TP-LINK TL-WR841N to broadband (BSNL).

      Internet access was working great in
      1. One of my laptops with Windows 8.1 OS was

      1. one Windows 7 laptop
      2. Nokia Lumia 520

      After trying every solution suggested in the web, I finally hit this site. My router’s default MTU setting was 1480, which I changed to 1430. Voila! the issue is resolved. Thanks.

    For me pnbmetlife and some other sites were not opening up, I started browsing for the solutions where most of the people are suggesting to change the DNS settings. However it was the MTU setting I updated from 1492 to 1430 as suggested above. And it started working. I updated the setting in my router itself.

  74. acemary says:

    I’m also having the same problem. But in my case I’m could not able to save the settings after manually configuring the DNS servers in router. I mean nothing happens when click save button. Any help?
