I am having the same problem i just got a new fiberoptic internet connection and since then my downloads, only on limewire, otherwise it is much faster than cable/dsl. My test came out to be nearly 15000/kbps download and almost 10000/kbps upload speeds. Does limewire have a problem with fiberoptic? cause when i connect to my neighbors cable wireless the speeds jump to what they should be. any help would be great because Limewire doesnt seem to have any answers just say the connection speeds dont matter.
