Here is How to Find Proper MTU Size for Network Determine the Correct MTU for Your Network 1460 + 28 = 1488 is the optimum MTU Setting.1460 Max packet size from the Ping Test.Therefore, you must add 28 to your results from the ping test. Please note that 20 bytes are added for the IP header and 8 bytes are allocated for the ICMP Echo Request Header. Now that you have the biggest packet size from the ping test, you will need to add 28 bytes. Once you’ve reached the packet size which does not fragment, increase the packet size in small increments and test again until you reach the biggest packet size possible that doesn’t fragment. If you’re getting the same results, drop the packet size down more and do the further test until you reach a packet size that does not fragment. Drop the packet size down by 10 to 20 bytes and test again.Īs you can see from the test above, our packets still need to be fragmented. You will now see your packets needs to be fragmented. Type cmd into the box and then press Ctrl+Shift+Enter on your keyboard to run the command as an administrator.Īt the Command Prompt window, type in the command below followed by the Enter key on your keyboard. To do this, please follow the steps below: You can get the correct MTU values for your connection by simply sending out ping request and progressively lower down your packet size until it no longer needs to be fragmented. When you’re having network performance issues such as the VPN connection is being timed out. Generally, if your MTU value is too big for the connection, your computer/device will experience packet loss or drop of Internet connection.
The maximum transmission unit (MTU) feature on your router allows you to determine the biggest data size permitted on your connection. How To Find Correct MTU Values on Windows? Setting the MTU on your home network to its optimal value can significantly improve your network’s performance. Most home networks are set to its router’s default MTU settings. Anything larger than the set MTU is broken up into smaller fragments, which essentially slows down the transmission. MTU, or maximum transmission unit, is the size of the largest packet that the network can transmit.
