Hi people,I am a user of MTNL broadband plan 599U from Delhi. Recently i am facing problems with my MTNL internet speeds. The speed comes for 10-15 seconds then, goes to 0. The process keeps on repeating after every 10-15 seconds. When i open a web page ,it keeps on loading for 10-15 seconds until the speed comes back, similarly, when i click on a link, it takes same time to open. When i download via torrent, the download speed comes for same duration and then vanishes. The lights in my modem (450TC1) dont go off. The lights are fine. I am very much bothered by this problem, please suggest a solution.
