I have disabled the Ultrapeer capabilities about 2 weeks ago as before I was connecting as a leaf or ultrapeer depending on the mood of the limewire gods. I still encountered the same upload and download problems even after making that adjustment. Not until my IP address changed did the problems vanish. Somehow I can't help but believe that there was some sort of an inherent glitch associated with my previous IP address. I don't have any problems now and people are once again able to receive uploads from me just fine and I'm able to download just as effortlessly now. Although I don't have a static IP, this is the first time I've had my IP address change on me in over 3 years. It's great to have things working flawlessly once again. It's been a long 3 or 4 weeks of frustration.
