Optimize Your Network Connection

For enhanced gaming performance, utilize a wired (Ethernet) connection during gameplay.
Minimize the number of devices sharing the same network to avoid congestion.
Periodically restart your router or modem to maintain optimal functionality.

Command Prompt Troubleshooting

To access Command Prompt, search for "CMD" or "Command Prompt" in your taskbar. Enter "ping google.com" to evaluate your latency to Google's servers and assess packet loss. If your ping or latency exceeds 100 ms or you detect packet loss, the issue may be linked to your network connection. Execute the "ipconfig /flushdns" command to clear and reset the contents of your DNS resolver cache.

End Network-Intensive Processes

Access your Resource Monitor by opening up your Task Manager. Right-click your taskbar to open up your task manager. Under Performance, select Open Resource Monitor. On the new resource monitor window, open the Network tab, where you must open the Processes with network activity.

Task Manager > Performance > Open Resource Monitor

After a few seconds, you will see every process using your network connection on your system. 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. In the tab below, you can preview your network utilization in percentage.

Disable VPN or Proxy Connection

Since the game has many simultaneous players on the same server. You can also fix server problems by trying to change the server region in the game. This will help you depending on where you are trying to connect from. You should also make sure that you are not using a VPN service as this will cause latency and packet loss when you try to play Modern Warfare Warzone. If the servers aren't affected, the problem could be on your end.

Windows Settings > Network & Internet > VPN

Change DNS Server Addresses

Network-related issues can be caused by your DNS server address connection. In this step, we will change it, as it should help many users with network problems.

Use the shortcut Windows Key + R, and in the dialogue box enter Control and hit enter. This will open up your control center. From there, navigate to Network & Internet, Network & Sharing Center, and here select your connection.

Network and Internet > Network and Sharing Center

Navigate to Properties, and lastly, double-click the Internet Protocol Version 4 as you can preview on the screenshot below. Select to Use the following DNS server addresses option, and as your preferred DNS server, use : 8.8.8.8; as your alternate DNS server, use: 8.8.4.4. These are the official public DNS server addresses from Google, which are safe to use.

Malware & Other Applications

We suggest removing malware and preventing applications from running that could use up your available resources or change your game files.

Verify Connection to ISP

If you still experience latency or lag issues, verify your connection to your Internet Service Provider. You can troubleshoot this step by changing your connection to your hotspot for example.

Delete Temporary Files

If you have issues loading maps or downloading other content, then make sure to delete your temporary files. Search for %temp% in your taskbar search to open up your temporary files folder. You can safely delete everything in the folder, some files might remain so just leave them there. This can help you reduce some clutter on your hard-drive.
