Hi Ben, Unfortunately I can't offer you any help because I am in the same boat as you with the same exact situation, same error using uTorrent 2.0, and my router is a D-Link DGL-4300. I found both of your posts, this one and the one on Yahooo Answers by doing a search in Google for the error we are getting. Hopefully someone can help us! I have another post at portforward.com in an effort to resolve this problem. Just for the record in this forum, I am going to post more details about my situation in case it helps: My Router is a DGL-4300 which shows the DHCP IP address range is between .100 and .199 and my former Static IP that I had setup was within that range. So I now setup my Static IP at out of that range at .250. I edited the Gaming Rule that forwards the port that uTorrent uses to allow the new .250 Static IP address. It just so happened that automatic update checking of uTorrent alerted me to the new version 2.0 at exactly this same time (what a coincidence), so I upgraded and am now running uTorrent 2.0. I confirmed that Windows firewall is still allowing uTorrent as an exception, and confirmed that uTorrent is still using the same suggested port as before, which I have forwarded in my router (and for the new .250 Static IP) . I ran the new Utorrent's setup guide/speedtest several times to different nearby networks and when it was testing upload speed it reported back the following error each time: Bandwidth: Results: Speed Test Failed. Data Send Error: A Local Networking problem closed the connection. (10053) Network: Results: Port is not open. (You are still able to download).
