shant wroteif you're on Firefox, if you go to settings and put save download to desktop
when you click on a download file a small window pops out and there's two button, "cancel" and "save file"
click none and you will still be downloading the file, at that high speed (which is 300kbps for you)
but as soon as you press save file the speed reduces, i don't know whats up with that
Shant, I just explained the whole thing...for a few days till now
