Yeah, I am getting 3-4 kBps on an upto 64 kbps pack (trying it for this month only) when I haven't reached the limit yet.Infact very infrequently I get 7-8 kbps nowadays. But if I am online at some unearthly hour like 3 AM I get 8-9 kBps on this :-|Ujjwal, you might want to try these ways to run the official Sify Linux client smoothly. I am only online using Linux nowadays and use the latter client only

Firstly, run even Sifyconnect as root. By doing so you get to see the "Logged In" message and your account info which we otherwise don't as a non-root user.Secondly, when you have some trouble logging in kill sifyd and restart it manually. That solves the problem for me often.
