If you're using uTorrent, then when you first run it, a "Speed Guide" should pop up. If it isn't the first time you run uTorrent, or it just hasn't shown up, then click "Options" then "Speed Guide" or just press "Ctrl - G" when you have uTorrent on your screen. Click the button that says "Run speed test at: www.dslreports.com" and test your speed. Then when you have your upload and download speed, go back to uTorrent, click on the drop down box that says "(Current settings)", next to "Connection type:" and select the speed that matches or comes closest to matching your upload speed.
