i agree with wizard.... i too keep my net on for 15 - 18 hrs on holidays, with the internet radio on in the background.... For the service provider, I'm downloading continuously then.....n these people have set the speed (some kind of programming, i donn know how they are able to do so) if u're r downloading continuously, u're speed are set back to original, n no more 2x at night, until n unless you reboot the modem, because of which I'm not able to enjoy 192 kbps stations (in the day, i somehow compromise with 128 kbps stations)
