RAFI thank you so much dude! I have tried many solutions as seen in this forum and none worked! A deeper search took me to this topic and voilá! I just followed B[1,2,3] and it tottaly worked for me. My problems started when i formated my pc. I was using win7 ultimate 32bits. New install with win 7 ultimate 32 bits, but slightly diferent version. I was having lots of peaks and oscillating speed. My web surfing was also very slow each time utorrent was dowloading (at very low speed). Its all good now, downloading at 1000kb/s ! ; ) TY
