I am using the MTNL 3G Jadoo datacard on my computer. The speed is normally not great, around 256 kbps, which is really nowhere close to the 3 mbps anticipated. But in the last couple of days the speed has sunk to about 15 kbps. Am wondering what to do and how to fix this. Is this because I have recently shifted to New Manglapuri in New Delhi? Is there anything I can do to solve this? Please help.
