I just got this error from Bittorrent on my NTL connection and I've also been getting poor download speeds- despite it being completely fine a few weeks ago.
I'm using the latest Azureus client, with no firewall and no router. I changed the port setting in Azureus and the download worked. Unfortunately, it's also been a bit up and down speed-wise. It started off at my connection's full speed, but keep slowing down to around 4/5kbps and then speeding up again. Right now it has levelled out at about 5kbps, although I'm uploading at a much faster rate- which leads me to believe it's something to do with NTL.
Is there anything else I can do to ensure it'll work better on my connection? What if I were to change my IP address in Azureus- would this make any difference and what should I change it to? What's all this port-forwarding and how would I stop the NTL proxy messing things up? Sorry for being a complete n00b, but if anybody could help I'll be extremely grateful!
