Changing the Maximum Transmission Unit (MTU) size in Windows 11 can be a practical solution for improving your network performance or troubleshooting connectivity issues. By following a few simple steps, you can adjust the MTU settings to optimize your internet connection. Here’s a quick guide to get you started.
How to Change MTU Size in Windows 11
Adjusting the MTU size can help improve your network performance or solve specific network problems. Follow these steps to change the MTU size in Windows 11.
Step 1: Open Command Prompt with Admin Rights
First, you need to open the Command Prompt with administrative rights.
Right-click on the Start button and select "Windows Terminal (Admin)". This is crucial because only an admin can modify network settings.
Step 2: Find Your Network Adapter Name
Next, you need to know the name of your network adapter.
In the Command Prompt, type netsh interface ipv4 show subinterfaces and press Enter. This will show a list of your network interfaces and their current MTU values.
Step 3: Change the MTU Size
Now, you can adjust the MTU size for your network adapter.
Type netsh interface ipv4 set subinterface "Your Adapter Name" mtu=XXXX store=persistent, replacing "Your Adapter Name" with the name of your network adapter and XXXX with the new MTU value. Press Enter to execute the command.
Step 4: Verify the Change
Finally, confirm that the MTU size has been changed.
Type netsh interface ipv4 show subinterfaces again to see if the MTU size has been updated for your network adapter.
After completing these steps, your new MTU size should be active, and you might notice an improvement in your network performance.
Tips for Changing MTU Size in Windows 11
- Always make a note of the original MTU setting before making changes.
- Test different MTU values to find the one that works best for your network.
- If you encounter issues, you can revert to the original MTU size using the same steps.
- Restart your computer after changing the MTU size to ensure the changes take effect.
- Be cautious with very low or very high MTU values as they can cause connectivity issues.
