My broadband- MTNL


When I enter my public ip address in google search, it opens some site after entering default username and password.

When I tried to update my firmware, I got stuck. See image-firmware upgrade

Now it ask locations, but I can't select a location. When I click choose file, it opens a dialog box but what file I choose I can't understand.

Never update firmware over WiFi. Nor from the upstream network. Never allow your router to be accessed from the world.

It is your router, correct ?

When you downloaded the firmware (!) Where did you save it?

Did you make a backup of your firmware ? Where did you save that?

The file should have the extension .rom or .bin - if it is compressed you may need to extract it.

It sounds like this question needs a localised answer, you should check forums and your ISP's help pages before coming here.

But seriously, disconnect from the internet first, and use an ethernet cable.

It is almost certainly a Beetel 450tc1, but your ISP may have a custom ROM image you may be required to use. This is likely given the custom logo.

Seriously as well, ask your ISP.

  • Totally agree with the upstream & wifi firmware update. This is a really easy method to get a permanent paper weight. (Bricksville router) +1 Jul 12, 2018 at 14:04
  • ISP is bad. Wont tell anything. Jul 14, 2018 at 12:32
  • Yes it is my router. Never downloaded firmware before. No backup. How do I update without internet? Site wont open without internet. I dont have ethernet cable. Can I use dongle? Jul 14, 2018 at 12:35
  • I dont have any .rom or .bin file in my computer which could be a firmware. Jul 14, 2018 at 12:41
  • @suyashsingh234 Then you probably do not need to update at all and you have just landed on the page. Maybe by clicking menu items before rendering had completed. When you type your IP address in, you see what the outside world sees at your IP. You need to close this. Instead use the local IP of the router, look on the bottom or back of the box. Change the password, disable ping response, disable internet logon. Get a friend to help you. Don't mess with the firmware version at all unless you have been clearly told to.
