I have a desktop computer. I have Windows 7 installed on it. I use a Micromax USB modem to connect to internet. Inside this USB modem, I have a BSNL 2 GB sim card. I get the maximum speed 1 or 2 Kbps. That is not constant also. Frequently it drops to 0 bps. Is there any method to increase the speed ? Will tweaking the registry of Windows help?
