Limewire & Bearshare seem to go by multiple sources. Meaning, the sources are there but not everyone opens up to allow other users to download. but if the source number keeps saying 6 for you, it's always a good idea to double check your setting. not so much your bandwidth, but the sources you are accepting from. How many sources do you have your Limewire set on? Again, sounds like you have yours set on default. go higher. it doesnt matter if you set your bandwidth to a hundred percent, you can only download as fast as the user you are downloading from. hope this helps?

edited to add: Keep in mind too that you are downloading off the gnutella (sp?) network not Limewire network, LW is just the app that allows you to connect. You have to find hosts or sources to download off of. Not sure what versions you guys use though. This is the same for all P2P apps whether it's Pro or free. If the host isn't online to allow you to download off of then, you'll have to try to find more sources who are online at the sametime you are.
