Configuring BSNL DNA-A211 ITI router/modem to automatically connect

If you have a ITI branded modem from BSNL, you probably wont find much documentation about setting it up for multi-use. The unit is actually an OEM product from SEMINDIA model # DNA-A211. This how-to will show you how to setup the router so that it automatically connects to the Internet on start-up, so that you don’t have to dial a connection.

First we shall setup the DSL connection:

1. Connectย  to the modem/router through Wired Ethernet and enter in the address bar. When prompted enter your username/password. It should be admin/admin by default. If you have forgotten the username/password, you can reset the modem by pressing the reset button on the back of the router with a pin for 10 seconds. If you can’t access the modem at try this.

2. Click on Advanced Setup -> WAN. You should see the following entries. The one we are interested in is the first one as shown. Click Edit.


3. Enter the settings as shown below and click next.





Now to setup your wireless access, goto Wireless -> Wireless Bridge and choose the following:


Also ensure that your wireless is enabled by going into Wireless -> Basic:


Also ensure that your DHCP is enabled by going to Advanced Setup -> LAN and checking that your DHCP is enabled as shown below:


Now go into Management -> Save/Reboot. This will save the settings and reboot your router. On restart the modem will establish the connection and you can simply connect to the wireless network.

Hope this helped. If you have any questions just ask in the comments section.

  14. Flashed Wrong Firmware on UTStarcom WA3002G4 ADSL 2+ Router/Modem? – Don’t worry! ๐Ÿ™‚


    Hello there,

    I would like to share my experience in fixing my UTStarcom WA3002G4 ADSL 2+ router/modem after having flashed it with some wrong default firmware present in the CD that came along with that modem purchased from BSNL. You can directly jump onto the steps if you don’t want to be bothered about my bitter experience in figuring out the feasible way to flash and the assumptions I have made therein.


    Though there are innumerable posts/threads in the internet on this, it was a hard time to figure out the exact steps to fix – flash my UTStarcom WA3002G4 ADSL 2+ router/modem with an appropriate firmware. Because, each of the threads/posts discussed about the steps to be followed in a discrete manner – leaving out some intermediate steps to follow. Of course, there would have been assumptions about the intermediate steps therein, but for an impatient person like me that approach seemed to be inadequately helpful.

    Well, enough of talking, let me tell you the steps I followed by which my UTStarcom WA3002G4 modem/router was reborn!


    Assumptions made(rather the state of my router/modem with the wrong firmware!) :

    1) Power LED is steadily lit.
    2) DSL LED is not lit(there is something about this DSL LED and Limited or No Connectivity I need to share. I will share in the end – Don’t want to obstruct the flow).
    3) No other LEDs are lit(duh!)
    4) You get Limited or No connectivity as the connection status after the wrong firmware flash. And yeah, you will see some fake IP-Address assigned by DHCP(not actually).
    5) After the modem/router is powered on and when you see the “Limited or No Connectivity”, is unreachable when you ping(Again, duh!)
    6) But, only while the modem/router is booting(just after the power up action), you could see a TTL value of 100 received by the ping action(ping -t The value 100 means that the boot loader is alive! Thank God! So, only task left is to restore the firmware and let the boot loader load that firmware – yeah, more of unnecessary info I am sharing – But, for the sake of clarity, I am compelled to do so!


    Here we go. Simple steps followed :

    1) Connect the router/modem to PC using ethernet cable and have the power adapter connected to the router/modem as well.
    2) Power on(duh!).
    3) Manually assign a static IP-Address to your PC(Any IP-Address would do as per my experience, say with subnet mask Don’t worry about other stuffs – Default Gateway, Preferred DNS, Alternate DNS, blah blah – Let them be blank. No problem. Now the connection status should be “connected” instead of “Limited or No Connectivity”.
    4) Switch off the router/modem using the power button at the back.
    5) Keep the hard-rest button(micro-switch accessible through a round pin-hole/tiny hole at the bottom of the modem/router near its right-leg(cushion) – Easily, this tiny hole can be missed amidst the square holes present to help in the ventilation) pressed with a refill/ball-point pen tip.
    6) Switch on the router/modem using the power button at the back – Keep it pressed for 2 secs before releasing – Better not to use technique – Plug-out and plug-in the adapter from socket – Reason? I will share in the end – Don’t want to obstruct the flow.
    7) After a short while(few secs), you will be able to see the ping command displaying receiving so and so bytes etc with a TTL value of 100(boot loader is up!).
    8) Now, in your PC browser keep on refreshing the page
    9) You must see a page asking to “choose a file” to upload the appropriate firmware – At this juncture I chose the BSNL Dataone firmware I had downloaded and my browser(Chrome) showed the progress of the upload in its bottom-left corner. There after it started showing the page with the information indicating it will take about 2 mins to flash the uploaded firmware and that the modem/router will automatically reboot thereafter(You should see the change in connection status from Network cable unplugged to plugged to Connected with Limited or No Connectivity as we yet don’t have the DSL connection in place once the flashing is done and the router/modem reboots).
    10) That’s it. The router/modem is reborn! \m/ If needed, reboot(soft-reset using the power button at the back) once and you shall be able to access the much needed – Time to celebrate! Note that the hard-reset button has to be kept pressed all these while(1-9 if needed until 10th step also). Otherwise, the boot-loader will move ahead and try to load the wrong firmware unaware of its incorrectness! Yeah, continuous ping(ping -t replies with TTL 100 is very crucial to the success of the flash.


    Left over information which I thought would obstruct the flow all these while :

    Well, now let me tell you the issue that I told of obstructing the flow all these while. It’s about the Connection Status – “Limited or No Connectivity”. Whenever I plug-out and plug-in the adapter from socket, no doubt the router/modem reboots automatically on its own as its power button would still be in pressed state. But, the IP-address assigned by DHCP(actually not) will be a fake one – 169.something.something.something and the connection status would be “Limited or No Connectivity”. The funny thing is the DSL LED would be well lit at this point! This same fake indication – DSL LED being lit happens also when the modem/router(when in powered off state) power button is pressed and released very fast – in a second. This very issue provoked me to re-flash my router with any firmware I had(invariably, I had a wrong one)! And the annoying Limited or No Connectivity I expected not to reappear once re-flashed. To me additional annoyance, the router/modem breathed its last breath when I fed it with poison in the form of wrong firmware.

    Okay, though the above “Limited or No Connectivity” is very much prevalent even after re-flashing when the above actions(plug-out and plug-in, and power outage and restore), my UTSTARCOM WA3002G4 modem/router is back in action after my 5-6 days of mental agony and struggle, saving some money as well!

    Hope this helps someone in future if at all has same problem, though its lengthy and has some unnecessary info here and there!

    For those who would be wanting to know the firmware I have used, here is the full file name – 3.08.BSNL_02.01.02_tr64._fs_kernel, size : 1.86 MB (1,953,751 bytes) and size on disk : 1.86 MB (1,953,792 bytes).


    PS : The “Limited or No Connectivity” issue has been discussed at great length across the internet. But, I have no luck after trying all sorts of things – especially, the approach involving the assignment of static IP-Address, sub-net masks, freely available public DNS server address. I somewhere read that it might be related to the voltage provided by the power adapter, though not sure and also haven’t thought of replacing it either. Let me know if anyone has a working solution for this.


    Have posted here to help those who would come here in search of a relevant solution in this blogspot. Thanks.

  15. Hi Sunny,

    I have a ITI branded DNA-A211-I Type 2 modem from BSNL. Someone the I gave it to, has gone and wrongly changed the firmware to a MTNL Type 1 modem. Now obviously the wi-fi bit has gone. I need to reload the original firmware of a Type 2 BSNL modem DNA-211-I. Do you know how I can go about doing that myself.

    I am ok doing most stuff such as configuring the modem etc. after change in firmware but I cannot seem to find the firmware anywhere. I have located an upgrade utility file 02DSW-700021_ModemSwUpdateUtility.exe but this gives a error message saying software mismatch. Help needed.

  16. hey sunny… i’m facing some DHCP problem with the router
    its an iti DNA-A211
    i’m unable to connect through wi-fi with my t.v n tablet.. while it easily connect to my laptop

  17. Hi Sunny, I have tried these steps. The problem i am facing is every time i wanna connect to internet i have to dial a connection from my Laptop. Due to this problem i am able to connect internet from Laptop but can’t connect it with my I-Phone.
    This was working fine before few days. Some days back BSNL engineer done some configuration changes and since then I am facing this problem
    I have verifired the configuration with the snapshots you have attached and all is matching. Suspecting some issue with Modem but not sure. Kindly suggest if you have any alternate way

  18. Hello Sunny,
    I have DNA-A211-I modem. I have a problem with wireless connectivity. I use wired connection for my pc & wireless connection for my laptop & samsung mobile phone. I am able to access the internet on pc very well (wired connection to modem).
    When I connect my laptop (having Windows 7) using wireless connection I get connected to the router correctly (I get ip address assigned to laptop). But I am unable to connect to the internet from it. When I try to open a site on browser it just shows me that it is connecting but the page never loads. Following are the things I tried doing,
    1) tried to ping www, (other sites too) on command prompt. The ping succeeds every time.
    2) tried to access the router config page (ip from laptop which gives me dialog box to enter user name & password. When I enter that (user : admin/pwd : admin) it goes further showing ‘connecting’ but it really never connects there. When I deliberately enter wrong password it shows me password error.
    3) Tried connecting wireless-ly using another laptop (windows xp). But I see same thing happening here.
    4) When I connect any of the laptops using ethernet cable the internet just works fine!!.
    5) Surprisingly if i connect my samsung android (2.2) mobile wireless-ly, it connects fine,
    6) I checked whether it could be problem of proxy settings of browser but it seems not the problem.
    7) I tried using 3 browsers IE, Chrome & firefox. Same problem for all of them.

    I am using this modem for almost 4 yrs now. I started seeing this problem since Jan 2012. Before that wired & wireless connections on the same laptops were working fine. I haven’t changed any configurations on the modem. Also I haven’t changed any configs related to network connectivity on my laptop.
    Could you please help me here? I think I should do a ‘Reset to factory defaults’ once for the modem configs. But before that I would like to have better solution if any to this problem. (I am not sure after doing reset to factory defaults it will work or not).
    Thanks in advance.

  19. Hi Sunny, Thanks a lot for the settings,
    I have done these changes, my mobile says connected to router and gives full signal, but I am not able to use internet, I can use internet on my desktop but not on my mobile. Can you please help.

    Router: BSNL DNA-A211 ITI


  20. Hi Sunny, great insight to wireless router, I am trying to achieve port forwarding for this model, challenge here is that the router runs on port 80 as default and my dynamic requests from internet comes on default port 80. when i try forwarding port 80 in router to my static IP for DVR.. it does not like.

    Any ways I can get the default port for router changed to 8080 or I dont care, any thoughts!


    • Yeah, you can change the port of the router to 8080 and forward requests on port 80 to the DVR.

      OR you can change the port for your DVR and use that to connect to the DVR.

      • Hi Sunny,

        Is there any documentation for changing from port 80 to 8080 for router?
        I see a error in log file declining it is not done.


  21. 1.My modem (DNA-A211-i) works well. But i try to connect my phone by WiFi i receive message “DNS failed”. How can i configure my modem to use it with wifi devices.

    2. How can wifi connection be password protected.

    • The DNS failed is because the default BSNL DNS servers are very unreliable. Use (google DNS server) as your DNS server.

      You can password protect the WiFi by going into the Wireless settings page in the router config.

  22. Hi sunny !i ve the same problem …i can’t save my configuration…it’s going to default settings always…pls do help!!!!!

  23. My mobile phone is Samsung Galaxy Ace with wireless and my BSNL modem is DNA-A211-1. I have configured my modem exactly as shown in the tutorial. However, I am still able to connect the my phone (via wireless) and desktop to the internet at the same time. When my phone is connected, the message shown when I connect to the internet from my PC is : “Phone line is busy”.
    I went to command prompt and typed “ipconfig/all”, which shows “DHCP enabled : No”, even though I have enabled it from my modem configuration page. Please help!!!

  24. i was able to connect my cell via wifi to my pc… but unable to use internet in my cel???? y???? has it got anything wid my wifi settings or else???

  25. Hi

    By following these steps, do we always have to keep the wireless security as Open?
    Because when I tried using WPA or WPA2 or other, it just won’t connect on wireless.

  33. My modem DNA-A211-I is configured by BSNL in it’s office-Subhanpura, Vadodara. On right bottom of my laptop there is signal strength icon. Since it has been configured by BSNL, that icon carries yellow triangle with ! mark. Although , clicking it shows ITI is connected but web sites do not open and shows error in connection. How is it that it shows connected and it does not connect. What to do for a wireless connection automatically?
    I am happy I found this forum. Thanks

    • The yellow exclamation mark means that the router is not connected to the Internet. The Wireless is working fine. Check that the phone line is plugged into the modem and your username/password in the router configuration page is correct.

  34. Sunny, I, a complete newbie, have a BSNL Nokia-Siemens black colored Modem & a Rs. 750 single user unlimited connection. I have a desktop & a laptop, connected with a D-Link hub/switch.
    The problem is when I connect my desktop with my bsnl id/pass it connects easily, but the laptop doesn’t or vice-versa.

    All I wanted to share the internet connection in both desktop & laptop.

    please help!!

  35. Dear sir,
    I am using Internet from local ISP who had given me connection using co-axel cable and a cisco modem and in the Modem it had only 1 RJ45 female connector from that it is connected to my desktop nic,every thing is working fine but i have 1 PDA and Laptop and a DNA-A211-1 Modem which was given by BSNL which i was earlier using.I was struggling to configure that modem so that i can use all the three systems but it shows connected on Wifi but sows page cannot displayed and total ISP communication is on DHCP.Regarding this I spoke to ISP they told me to buy a router BSNL modem will not work,Does this modem fulfill my requirement or I need to go with new one.

  36. Hi sunny … Thanks a lot for your post here…

    I bought a new BB connection. I have DNA-A211 ITI modem with me. since i own a modem they refused to asssit me to configure and connect it. By following the above steps can i connect to the internet directly and start browsing? what is the use of the username and password they gave me?
    Plz reply …

    • Just follow the steps on my blog and it should work just fine. The username and password is used by your router to connect to BSNL.

  37. hi sunny………
    i’am raju. i have a problem that every time am switching on my computer i wanna give the user id and password in…..

    I mean the problem is the user id and password is changing to then am again want to reconfigure.this problem is going on please give me a solution to this problem

  38. Thanks sunny for your quick reply ….

    i have checked the DHCP setting , it is exactly same as your setting.

    but i am not able to connect internet to from both (lappy n desktop) at a time.

    waiting for an early reply …

    thanks a lot … ๐Ÿ™‚

      • hi sunny …………even i m facing the same prob…….when other device is connected on wireless…….i cannot access net on my desktop tht doesnt have wi fi capability……..on the other hand when i restart the modem and connect thru dial up on desktop……the other devices r unable to connect though they r detecting the wi fi correctly………

      • It’s because your modem/router is not configured properly. If you follow the instructions in this guide it should work.

  39. Hi Sunny !!

    After reading your tutorial , i am able to configure my (ITI DNA A211-1 ) modem in auto dialing mode . But i am not able to connect LAPTOP and DESKTOP simultaneously to the internet ….

    I simply want to connect both (laptop and desktop) to the internet simultaneously even without auto dialing mode.

    Hope …. you will help me out .

    Thanks ..

  40. hey sunny at the outset–thanks.
    but im still not able to connect wireless however it connects with the help of a cable.
    i got this router from bsnl-bangalore. now i’ve moved to delhi n ve taken a mtnl internet connection.
    can u help?

    • The ISP has nothing to do with your wireless settings. The fact that your Internet works when connected by wire shows that your DSL link is fine.

      Try to follow these steps again to setup your wireless.

  41. hi,
