I had installed Netgear CG3000D router in my room. I am having a very slow speed. This use to work really fine when it was new. But now it is quiet slow. I have a broadband internet connection. I easily get 60kbps of speed constant. But in the router getting around 10 to 15kbps only. What can be the problem. And it also not placed on a very long distance. What should I do.
