78kB p sec

hey mates

bought a mobilnet at '3' store called all-u-can-eat-data. Useing an e51 Nokia as modem via usb cable.
When im downloading with utorrent i cannot download with max speed cause it keeps disconnecting. I figured out if i set max download speed to exactlz 78kB sec then it keeps downloading. So what should i do?
I guess i should use some program that reconnects my inet everytime, or smth. any idea?

cheers
