In today’s digital age, a fast and reliable internet connection is essential for seamless browsing, streaming, and downloading. One factor that can significantly impact network performance is the Maximum Transmission Unit (MTU) size. In this article, we will explore how to set the MTU size in Windows 10 to optimize your network performance.
The MTU refers to the maximum size of a packet that can be transmitted over a network. By default, Windows 10 sets the MTU size to 1500 bytes, which is suitable for most networks. However, in certain cases, adjusting the MTU size can enhance network efficiency and reduce latency.
To begin, we need to access the Command Prompt in Windows 10. Simply press the Windows key + R, type “cmd,” and hit Enter. A black window will appear, allowing us to input the necessary commands.
To check the current MTU size, type “netsh interface ipv4 show subinterface” and press Enter. This will display a list of network interfaces along with their respective MTU sizes.
Now, to change the MTU size, we need to use the “netsh” command. Type “netsh interface ipv4 set subinterface `Local Area Connection` mtu=1472 store=persistent” and press Enter. Remember to replace “Local Area Connection” with the name of your network interface if it differs.
After executing the command, the MTU size will be changed to 1472 bytes. This value is commonly used when dealing with Virtual Private Networks (VPNs) or when fragmentation issues occur. However, feel free to experiment with different MTU sizes to find the optimal value for your network.
To verify the changes, type “netsh interface ipv4 show subinterface” again and press Enter. The updated MTU size should now be displayed.
It’s worth noting that changing the MTU size on your Windows 10 device alone might not guarantee improved network performance. Your router and other network devices also play a crucial role. To configure the MTU size on your router, you will need to access its settings through a web browser.
Open a web browser and enter your router’s IP address. Usually, it is mentioned on the router itself or in the user manual. Log in to the router using the provided credentials.
Navigate to the WAN Setup or similar section in the router settings. Look for the MTU Size field and enter a value between 64 to 1500 bytes. Click the Apply button to save the changes.
By adjusting the MTU size on both your Windows 10 device and your router, you can ensure optimal network performance and reduce the chances of packet fragmentation or latency issues.
The MTU size plays a crucial role in network performance. By following the steps outlined in this article, you can easily set the MTU size in Windows 10 and optimize your network for faster and more efficient connectivity. Remember to experiment with different values to find the perfect MTU size for your specific network configuration.
