Here's the link to test the port. Yep, tried it and it said the test worked.

Ok, so it sounds like my computer is not receiving the incoming connection request. I'm not using a router but I am using a hub. However, the results are the same whether or not the hub is in the loop.

Also, it seems my success is intermittent. As an experiment I DL'd a file and I got a good DL speed. I deleted it and waited 10 minutes and DL'd it again. Good speed. I repeated this 6 more times and I only got three good DL's...the rest sucked.

Still trying to wrap myself around this incoming connection. Would any of the settings in Phex's firewall/proxy menu affect my situation?
