I have recently downloaded TCP Optimizer and run it on my laptop.
and after that it gives me an amazingly great speed of upto 1.23 MBps.

but after 1 and half days it was reduced to 30 KBps.

I am using a GPRS connection on my mobile.
I am having Windows XP SP3 on Laptop.
can you please tell me that why it is so happened?
what should i do to get the same speed.
Please see the « SpeedGuide.net TCP Analyzer Results »
