How to Set MTU on Windows 10: A Step-by-Step Configuration Guide

Setting the Maximum Transmission Unit (MTU) on Windows 10 can optimize your network performance. Essentially, MTU determines the largest packet size that can be sent over a network connection. Adjusting this setting can help solve issues like slow internet speeds or connectivity problems. Here’s a quick guide on how to do it.

How to Set MTU on Windows 10

In the following steps, you’ll learn how to change the MTU value on your Windows 10 machine. This can help resolve network issues or improve overall internet performance.

Step 1: Open Command Prompt

Open the Command Prompt by pressing Win + X and selecting "Command Prompt (Admin)" or "Windows PowerShell (Admin)."

This step ensures you have administrative privileges to make changes to the network settings.

Step 2: Find Your Network Interface

Type netsh interface ipv4 show subinterfaces and press Enter.

This command lists all network interfaces and their current MTU settings. You’ll need this information to identify which interface you want to change.

Step 3: Change the MTU Value

Type netsh interface ipv4 set subinterface "YOUR INTERFACE" mtu=NEW MTU VALUE store=persistent and press Enter.

Replace "YOUR INTERFACE" with the name of your network interface, and "NEW MTU VALUE" with the desired MTU setting. This command will change the MTU value for the specified interface.

Step 4: Verify the Change

Type netsh interface ipv4 show subinterfaces again to confirm the MTU value has been updated.

Double-check the MTU value to ensure the change was correctly applied. If it hasn’t changed, try repeating the steps.

Step 5: Restart Your Computer

Restart your computer to apply the changes.

A restart ensures that all settings are properly applied and the new MTU value is in effect.

After completing these steps, your network settings will have updated MTU values. This can lead to improved network performance and resolve any related issues you were experiencing.

Tips for Setting MTU on Windows 10

  • Always back up your current settings before making any changes.
  • Use a tool like Ping to test different MTU values and find the optimal one for your network.
  • Remember, the default MTU value is usually 1500 for Ethernet networks.
  • If you experience issues after changing the MTU, revert to the original settings.
  • Some ISPs may have specific MTU requirements, so check their guidelines.
