-Please consider the following-

*Note-these are not a definite solution just a few possiblities

1. What type of internet connection are you using?
2. Do you have a firewall or anti-virus program running?
3. Are any messanger programs running while your playing?
4. Anything downloading while playing?
5. Do you have an intenet connection? =P

I find these factors things to greatly effect my connection during online gaming,
Causing all sorts of problems. Consider them and see if it makes any impact.
When firewalls and antivirus are enabled it somtimes causes problems, along with
the messanger or P2P programs or any updates. Close your bowsers and windows
as well.

I posted this on another post about network connection problems. However one thing to add.

Make sure your system meets the requirements for the game. Video card is a big one. Make
sure it can keep up with the game if not then you will most likely get alot of lag.

There really is almost an unlimited number of things that could cause lag and connection
problems within your computer. Then again maybe the server is having trouble.

---Hope this helps with everones lag problems. Feel free to recommend this. Or make a
sticky on this topic.
