[Mr.X]

I am using a wireless connection to access the net.I am unable to download any file(.avi, .pdf) using Bittorrent client(ofcourse using those related torrents). These are the following error messages I got in Bittorrent software log file:

WindowsUPnPException : none port_collection (XP)
Problem connecting to tracker
Discovery timed out
NAT Traversal warning (XP: Unable to detect any UPnP services)
Problem connecting to tracker

Please help me in this. I have tried every possible other methods, used different torrent client software. It is just impossible.Please again help me.
