If you have a BSNL DSL W200-SY ADSL modem chances are, you have encountered a couple of problems with this particular type of modem. One is the DHCP issue and other is the modem setup page not opening with ‘admin’ username and password. Today I am going to explain how to solve these issues with a simple firmware upgrade.
What are the existing problems?
- DHCP issue: When your modem could not assign an IP dynamically to its connected host, this particular type of problem arises. Due to DHCP problem when you try typing ‘ipconfig’ command on cmd it will only show you the IP address as 169.254.×.× instead of 192.168.1.×. Also, the default gateway field will remain blank. This particular type of IP(169.254.×.×) is called link-local IPV4 address. The 169.254.×.× range of IP is reserved by Microsoft for private network addressing when a host fails to get IP from the connected modem or a router. As a result, you won’t get the internet. If you want to know more on this problem please see this article- DHCP issue of modem/router.
- Modem setup page or configuration page issue: When this type of problem occurs you won’t be able to access the modem setup page. The login with usual username and password( in this case admin) fails to open the page. If you are using chrome, you might get a repeated message saying the connection to the site is not private.
All you need to do is upgrade the firmware to get rid of these problems.
prerequisite: keep your broadband username and password handy before upgrading the firmware because we are going to hard reset the modem.
How to upgrade the firmware?
First of all, download the firmware from the link given below:
Download-BSNL-DSLW200-SY-firmware.zip (21857 downloads)
Step 1: Reset the modem
Press and hold the reset button placed on the back panel of your ADSL modem. Release the button after 15-20 Sec once the LEDs on the modem starts flickering. Wait for 1-2 minutes and try opening the modem setup/configuration page with 192.168.1.1.
Step 2: Backing up ROM file
It is always a good practice to back up your modem’s ROM file.
Go to Maintenance→Firmware→click on ROMFILE SAVE
Step 3: Upgrade
Go to Maintenance→Firmware→ New Firmware Location→ choose file
Browse the firmware that you have downloaded and click on upgrade. Wait for few minutes before it asks to put username and password.
Step 4: Reconfigure your ADSL modem
After upgrading the firmware you need to reconfigure the modem. If you don’t know how to configure the modem, don’t worry, we have everything you need. Read this article- How to configure BSNL DSL W200-SY modem. I hope this helps you.

I have liked. :)
Thanku
Can someone confirm that the issue is resolved?
It looks to be the same version of FW that my modem already has with the troubles.
Please
Hi Daren, have you upgraded the firmware? If so, what problem are you having now?
I have unch of these modems purchased from BSNL and having this problem.
I just upgraded your FW on one of it and waiting. I see that the FW version details remains the same.
Normally this problem comes after one day of resetting the router.
Can not open 192.168.1.1 page, can not login with admin.
Ok daren, do one thing. Put ip address manually on your LAN. Check this link for detail info

Hi, Prabhakar,
I am assigning IP manually. No DHCP. DHCP is only for wireless connections.
Oops, i think the the problem is within the modem. Daren, are you getting the ping reply from your modem?
When there is a problem or want some MAC to add the list, I can not access the modem.
All the way I have to reset, reconfigure and when there are 25 modems at a place you can imagine the trouble!
Does the manufacturer exist?
Can we contact them?
I tried to contact them by searching on google. But no luck.
Ive tried everything and ive factory reset d device twice using dt button on d back of d router but it still says "ur connection to this site is not private" nd login admin nd passwrd admin is failing...is dere a setting in d netwrk n sharing centre dt i can change o some xyz service
Hi Shardool, i suggest you to reset it one or two time more. Sometimes it needs multiple hard reset to make it work. So go ahead and reset it one more time. once you reset the router, you need to do two things, first update the firmware and then change the default ip address of your router to something other than 192.168.1.1. you can do so by going to LAN tab of your router. Make it 192.168.1.3 for example. Check this link: https://bpedia.co.in/how-to-change-ip-address-of-a-router/
please do inform if it works for you.Cheers.
Quick question! Is this a good modem? Should I replace it and buy something like TP-Link? I did upgrade the firmware and the issue is resolved. However, I feel like 1700 Rs is too much for this modem. What do you think? Also, may I know the source of the firmware file so that I can keep tabs on the update. If you rewrote the firmware, kudos to you! Can you share the source on GitHub?
Hey there, glad your problem was solved. As long as it is working, keep it. Besides it has 5 years of warranty period too.
Still if you are not satisfied or you need some extra fancy features, you can go with D-Link modem router rather than TP-Link.
Nope, i did not write it, i got it from one of my friend. Cheers.
Thank you for your quick response Prabhakar. Is it possible to get the source code of the firmware? I'd really like to see what the issue was and how it was patched.
Not sure about that. I have tried to contact the manufacturere several times, but there was no proper contact information provided anywhere. Sorry about that.
I actually tried it myself and then found your blog. I was hoping that you could contact your friend and ask him how he patched it. I honestly would like to know about the patch as it could help a lot of people if the 'fix' is open sourced or known. I see a lot of forum with unanswered questions. Hope you could help! :) I hope a tech savvy person like yourself would understand!
Sure. Drop me a mail at admin@bpedia.co.in. I would let you know if i got anything worth sharing. Cheers.
I was not getting internet today. Modem LED for internet was red. I registered a complaint to BSNL through phone in the morning and called one of the BSNL engineers in our area to know what is the problem exactly. He told me that there is virus attack , and a lot of BSNL modems in our area have been affected. He asked me to bring the modem tomorrow to BSNL office to reconfigure it.I was not so patient to wait one day to sort the problem out. I tried to enter the modem by typing IP address 192.168.1.1, but it was not opening. Then I searched web sites for help, and met yours. I followed instructions exactly as you mentioned here and succeeded. Thanks a lot, May Allah bless you.
Sir, that was one hell of a compliment. Thanks a ton. Keep inspiring.
