Chirag, he's not the guy who started the thread, if you didn't notice.
tarak162, you are talking about the balloon that pops up when you connect to the internet which says that you are connected to a Local Area Network with a speed of 100MBps. That is not your internet connection speed (if only we could have that kind of speed in India!) but the LAN speed of your service provider. You need to tell us who your ISP is. Is it BSNL/MTNL, AirTel, Sify, your local cable-waallaah or some other provider? And what is the speed of your internet connection? I am guessing it should be 256kbps.
Also, please note whether the speed you are getting is 5 kbps or kBps? That makes a huge difference. 5kBps would mean 40kbps.
