Improve your Network Connection

If you're experiencing connectivity issues with Modern Warfare, it's important to check your network connection. Using a reliable network connection can help reduce the risk of packet loss and improve your overall gaming experience. If possible, try using a wired (ethernet) connection. Additionally, restarting your router or modem can sometimes help resolve network issues. If multiple devices are connected to the same network, try reducing the number of devices using the connection. Finally, consider changing your network connection to see if this resolves the issue.

End Network-Intensive Processes

Open up your task manager and navigate to your resource monitor. In the Network tab, open the Processes with network activity, and after a few seconds, you will see every process using your network connection. This might be your browser running in the background, Steam or a download bottlenecking your connection. We suggest you only end the processes you know won't break your operating system.
