the maximum transfer of 256kbps netsetter is 22kbps. as usual we don't get this speed. the best time to use internet is after midnight ie.3am to 5am because at midnight many of them chat at this time . internet speed depends 80% on ISP and 20% of user ,we can only make changes in this 20%.main reason for the slow down of internet is isp, until india become developed there will be the same speed.
another way to increase spead is to use new network service provider ie,when a company or SIM (videocon) is lauched it donot have much users at starting as a result you get more speed than others
