When i got beetel modem its firmware version was V01.00.05_2_Test3, i suppose its latest already. And it was disconnecting very often.
When i complained to cc, the installation guy called back and said he will send me email of latest firmware.
He did send the email but its firmware version was same as the one of my modem i.e 777VR1_V01.00.05_2_Test3..img. So i did not installed it. And kept using the same way for one weak with disconnections.
But 3 days ago i said lets try that firmware given by the guy even if its same, and i instlalled it. And to my surprise its not disconnecting anymore. Hardly once in a day.
I am not sure how is it different even though it says same version number. But i am glad i got rid of disconnections finally.
If anybody need that firmware, lemme know.
