Alok you are posting in wrong thread... you must create your own thread.. to do that simply click on "New Thread" button at the bottom right or top right of forum area.

Now regarding your problem, I think you must consider contacting help/support area of modem vendor or read its manual. There might be something you are missing. so just check its manual one more time.
