well if you stay connected for a long time (several hours) you should switch to ultrapeer once you can't find an ultrappeer to take you as a leaf. Alternativly, you can either boot off connections to your three ultrapeers until you get ultrapeer or restart limewire after a couple of hours. Another mean is to play in limewire props to force you to be an ultrapeer. If you have the connection and computer as you stated, being naturally an ultrapeer is a matter of time.
