It could be a clue but.... I have yet to see anyone ask for or for you to post a tracert. This would let us see the entire network from you to the server that you are playing on. The problem may not be on your end at all. It may be an issue in cyberspace or on the servers end.
To do a tracert...
type in CMD
in the command window type... tracert XXX.XXX.XXX.XXXX (replace the X's with the IP of the server your playing on)
and then copy and paste the results here
