Plutonium

well, my laptop is connected via wifi while my pc uses wire conection, and in my pc plutonium works great, so surely that is the issue

I recently installed MW3 Plutonium and on every single server I have this lag thing that constantly teleports me 1 or 2 meters away every 5 seconds more or less. But while playing BO2 I have no lag issues, does anyone know why could this happen?
