Ethernet switches from 1GBps to 100mbps when playing games

Troubleshooting Ethernet Speed Issues While Gaming: A Common Dilemma

As a gamer, maintaining a stable and fast internet connection is crucial for an optimal gaming experience. Recently, I’ve encountered a frustrating problem with my Ethernet connection while indulging in my favorite games. I own a B450M Mortar Max motherboard paired with a Ryzen 5 3600 processor and a GTX 1660 Super graphics card. Despite the robust hardware, I’ve noticed that my Ethernet speed drastically drops from 1 Gbps to 100 Mbps during gameplay.

To keep my system cool and sustain optimal performance, I often have to increase the fan speed. However, I’ve discovered that when I play Call of Duty: Modern Warfare on the extreme profile through MSI Dragon Center (or even on the balanced setting), the Ethernet connection consistently drops after about a year of use. This issue has become increasingly annoying, hindering my gaming experience.

If you’ve faced similar problems, you’re not alone. Here are some potential solutions that might help resolve these frustrating Ethernet speed fluctuations during your gaming sessions:

Update Network Drivers: Outdated or corrupted network drivers can often lead to connectivity issues. Make sure your Ethernet drivers are up to date by checking the manufacturer’s website or using a driver update tool.
Check for Overheating: Ensure your PC’s components are adequately cooled. High temperatures can cause throttling, which may affect network performance. Regularly clean dust from your system and consider improving your cooling solutions if necessary.
Adjust Network Adapter Settings: Navigate to your network settings and look for advanced options. Disabling power-saving features for your Ethernet adapter might prevent it from switching to lower speeds during use.
Inspect Cables and Ports: Sometimes, the issue might originate from faulty Ethernet cables or ports. Consider testing with different cables or ports to rule out any hardware malfunctions.
Run Network Troubleshooter: If you’re using Windows, the built-in Network Troubleshooter can help identify and fix issues with your connection. Simply navigate to your settings and run the troubleshooter to see if it can resolve the problem.
Consult Community Forums: Use platforms like Reddit or tech forums to share your concerns and see how others have managed to solve similar issues. You may discover community-driven solutions that have worked for others.
