I'm not sure if you can get a real solution here for such a specific problem.Only your ISP can help you in this. If they don't respond to your call, going to their office might work. And if you are so badly frustrated, just witch the ISP.

With my little experience here, I doubt if we have any spoke person from MTNL on this board.

I'd also have to agree and say for a problem such as this, your isp should be your first call. Most these days have a way to check the stability if your internet connection and line, as with a problem like this, either or even both could be at fault.

while your connection is active, try to listen to the dial tone. If there is background noise, try replacing the splitter.

ok.I will call them.But mostly they say they will send someone to repair but they take like many days to come to my home.If that won't work anyone can suggest a good ISP with not so expensive net plans.I am a gamer so i probably need to download games and games these days are mostly 10 GB+ so please recommend me some good ISP according to that.
