This error can be a major roadblock to enjoying your gaming experience, but fear not, as we have a comprehensive guide to help you troubleshoot and resolve this issue step by step.

Step 1: Check Activision Server Status


The first step in resolving the "networking failed to start" error is to check the Activision Server Status page. This crucial step will allow you to determine whether the issue is on your end or if there are server-related problems causing the error. Navigating to the Activision Server Status page, which is typically available on the official Call of Duty website, will provide you with real-time updates on server status.

If the server status indicates that there are no ongoing issues, the problem may lie within your own network setup or system configuration. On the other hand, if the server status shows that there are known problems, it's likely that the error is due to server-related issues, and you can rest assured that the problem is being addressed by the game's developers.

Step 2: Troubleshoot Your Connection



Assuming the Activision servers are operational, the next step on How to fix MW3 ‘networking failed to start’ to focus on troubleshooting your own network connection. Begin by restarting your router to establish a fresh connection. Oftentimes, a simple router reboot can resolve connectivity issues by clearing any network congestion or temporary glitches.


In addition to restarting your router, ensure that your PC and Windows operating system are up to date. Outdated software can sometimes lead to connectivity problems, so installing the latest updates for your operating system and drivers is crucial. Additionally, it's important to disconnect from any Virtual Private Networks (VPNs) that may be interfering with your connection to the game servers.


Another essential step in troubleshooting your connection is to create a Firewall exception for MW3. This allows the game to communicate seamlessly with the servers without being blocked by your system's security settings. By configuring your firewall to permit MW3 to access the internet, you can mitigate potential connectivity issues related to firewall restrictions.


Furthermore, verifying the integrity of your game files through the game client can help identify and resolve any corrupted or missing game files that may be contributing to the "networking failed to start" error. This process involves the game client comparing your local game files to the files stored on the game server, ensuring that they match and are free from errors.

Step 3: Contact Activision Support


If the aforementioned troubleshooting steps do not resolve the "networking failed to start" error, it's important to consider the possibility of being banned or blacklisted from connecting to the servers. In such cases, reaching out to Activision Support is crucial to seek further assistance and clarification on your account status.


When contacting Activision Support, be sure to provide a detailed account of the troubleshooting steps you have already undertaken to address the error. This information can help the support team better understand your specific situation and provide targeted assistance to resolve the issue.
