Maybe someone will come along that knows this problem.
But its been a while, so I wanted to add my input. What ever you have for a carrier, be it cable, sat, you should go to speedtest.net, test your lan speed, if using onboard lan, or wireless.
If you are over 3 Mbps, then your network speed is not the problem. If you have cable, it will be a lot higher, depending on plans of your carrier.
So now if you get the speed problem out of the way, you have some other things to look at. Router, firewall, and the game installed, if none of these seem to be the problem, start testing drives, memory.
After testing your speed and find its ok, I would google your problem- such as world of war loading to slow, firewall setting for game and other settings.
You just might find a post that had this problem and solved it, hope it works out for you.
