I am experiencing what sounds like the exact same behavior and it only started within the last 2 days. Basically uploads behave as before. Downloads start off fine; e.g. 4 hosts, speeds in the 20-30 KB/s range. Network strength is high, I have measured my broadband speed, and all those specs seem fine. I was also able to download using BitTorrent and that worked fine as well. But after about 5 minutes the Limewire download speed goes to zero even though the status shows downloading from 4 hosts. And the speed just stays at 0. I have tried this at night, early in the morning, same results.

I am on Mac OS 10.4.9, but I doubt that is a factor.

Does anyone else out there have a suggestion. Again, everything worked fine until the last couple of days.

thanks
