Yeah what you are saying is pretty much it.Do another thing, go to the Sify Broadband folder on your computer and open the file debug.log. Look for the words "HBS Enable" in it and check whether it says "HBS Enable=Y" or "HBS Enable=N", the former meaning that your Heartbeat is still enabled and the latter meaning that it's been turned off Another thing. Which version of Sify's official client are you using? Are you using the upgraded version 2.6 or using the version 2.52?
