When I am playing games such as Counter Strike: Source or Call Of Duty: Modern Warfare 3 or any other multiplayer FPS game I have lags, they jump to 400 ping.
Windows 7 Ultimate 64-bit
Intel Core 2 Duo CPU E6750
Memory 2G RAM
My Network interface controller is bought from Edimax and my router too.
IMPORTANT INFO: my fps is high 200-150 average.
I would like to know if my lag problem comes from my Internet Card, Router or something else,
