Internet connection getting disconnected often

A

I have BSNL 2 mbps plan and I use WA3002G4 modem .
When i try to power on the modem, all the lights in the modem are on which means there is no problem with the connection but I am not able to connect to the Internet.
I then went to the router configuration page(192.168.1.1), an I simply click on the reboot router button .
After about 2 minutes, I was able to connect to INternet again...

This is happening often (not always). I also exchanged my modem with a friend(same model), again I am facing this issues. But at my friends home the modem is working fine... All this happened in our Old home

We recently moved to a new home about 500 meters away(just transfered the connection so I have the same Landline phone number), but surprisingly I am facing this problem in my new house also...

Where could the problem be.. Any work around for this??

This may be because of the line problems. Call up bsnl local office and get the line checked.

Yes, thats a BSNL problem.
And worst thing is that you cannot do much when you are dealing with BSNL

As BSNL to get your line checked. And IMO you should get a better after market router instead of BSNL.
