What is Packet Burst and What Causes it?

Information over the internet is sent and received in the form of packets. In online games such as Modern Warfare 3, data packets are transferred between the game servers and your device. However, when the rate is faster than the normal flow of network traffic, a burst happens. As a result, there are network jitters, frame drops, stutters, increased latency, and unexpected game crashes.

Here are some factors that could cause packet bursts:

  • Unstable or Poor Internet Connection
  • Network Congestion
  • Compatibility Issues
  • High Graphics Settings
  • Game Server Issues

Quick Answer

To resolve this issue, simply restart your PC and launch the game again. If that does not help, troubleshoot your internet connection and make sure that the device is connected to a fast and stable source.

Method 3: Switch to Wired Internet Connection

Wired connections are usually more reliable for high-speed internet connection than wireless connections as they are less susceptible to interference caused by external factors. Moreover, they have lower latency and have less chances of packet loss or burst. Hence, we suggest you connect the PC to the router via an ethernet cable to use the internet.

Method 6: Execute Port Forwarding

Post forwarding lets incoming network requests pass through any specific port, router, or firewall and directs them to the device within a local private network. Now this can not only make your network connection more stable and fast but also resolve minor glitches that could be causing the discussed issue.

Before you can forward a port you must write down and save the following info:

If you cannot detect the address of your router, refer to our guide on How to Find My Router’s IP Address?

Here you will see IP address next to IPv4 Default gateway.

1. In the URL bar of any web browser, enter your router’s IP address.

Note: If you get a privacy warning that says Your connection is not private, click on Advanced, followed by Proceed to <IP address>.

2. Now login to the dashboard with the router’s admin credentials.

3. Navigate to the Port Forwarding section and type your PC or gaming console’s IP address in the applicable box.

4. Now, enter the TCP and UDP ports of Modern Warfare 3 in the respective sections. Once done, Restart the device and check if the issue is fixed.
