MW2 Lag

[Zhandarr]

Seriously, Aaaah, is there any way to fix this? I live in an area with wifi, and I go on other online games all the time. Is there any other reason my MW2 lag is so bad? I try to move forward a tiny bit and I FLY.

If you are trying to play online from a wifi signal, it is going to be very laggy no matter what you do.

I would suggest getting an ethernet cable and plugging it into a wall, most likely near the phone line.
