how to change mtu on windows 10
Changing the MTU (Maximum Transmission Unit) on Windows 10 involves a few straightforward steps that help optimize your network connection. MTU determines the maximum size of data packets sent over a network. To make this change, you’ll use Command Prompt with Administrator privileges to adjust the settings. Follow along for a step-by-step guide to fine-tuning your MTU for a better online experience.
Step by Step Tutorial for Changing MTU on Windows 10
In this section, you’ll learn how to change the MTU on your Windows 10 machine. Adjusting the MTU can help improve network performance, especially if you’re experiencing lag or connectivity issues.
Step 1: Open Command Prompt as Administrator
To begin, you’ll need to open the Command Prompt with elevated privileges.
Right-click on the Start button and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)". This ensures you have the necessary permissions to modify network settings.
Step 2: Identify Current Network Adapter
Next, you need to identify the network adapter you want to change the MTU for.
Type netsh interface ipv4 show subinterfaces and press Enter. This command will display a list of all network adapters and their current MTU settings.
Step 3: Choose the Network Adapter
Find the name of the network adapter you want to change.
Look for the adapter that corresponds to your active network connection. Note down its name exactly as it appears.
Step 4: Change the MTU Setting
Now, you can modify the MTU setting for your selected adapter.
Type netsh interface ipv4 set subinterface "YOUR_ADAPTER_NAME" mtu=NEW_MTU_VALUE store=persistent, replacing "YOUR_ADAPTER_NAME" with the name of your adapter and "NEW_MTU_VALUE" with the desired MTU value. Press Enter to execute.
Step 5: Verify the Change
Finally, confirm the MTU value has been changed successfully.
Run the netsh interface ipv4 show subinterfaces command again. Check if the MTU value for your selected adapter has been updated.
After completing these steps, your network connection should be optimized according to the new MTU value. This can result in a smoother and more reliable online experience.
Tips for Changing MTU on Windows 10
- Experiment with different MTU values to find the optimal setting for your specific network.
- Common MTU values to try are 1500, 1492, and 1480.
- If you experience issues after changing the MTU, you can revert to the default value.
- Use online MTU optimization tools to determine the best MTU for your network.
- Remember to test your internet speed and connectivity after making changes.
