Change MTU

MTU (Maximum Transmission Unit) is the largest data packet that a network device can accept and across the data link, it is measured in bytes. Many users have faced MTU problems while tunnelling VPN traffic. SO changing MTU will help you resolve this issue.

There are two ways to change the MTU, one of them is easier and in the other, you need to run some commands.

Contact your VPN provider

This is the easier method, the Mtu can only be changed by the admins of your VPN provider. You have to contact the admins of your VPN provider and ask them to change the MTU in your connection profile. Many VPN services require more network packets. It usually is auto-adjusted to 1500 MTU, and below 1400 MTU works well with most of the services.

Through Comand prompt

Changing MTU on your own is possible and if you want to change the MTU on your own then follow the steps below:

  • Open the command prompt as Administrator.
  • Run the command netsh interface ipv4 show subinterface, this will give you the name of the interface you are connected to.
  • MTU is given on the left side of the screen beside your interface name. If you see the MTU is 1500 or above then bring it down to 1400 or lower.
  • To change the MTU run this command netsh interface ipv4 set subinterface “Wi-Fi” mtu=1400 store=persistent, you can change the MTU as per your need.
  • You can verify whether MTU has changed or not by running the command netsh interface ipv4 show subinterface again.

Run and reconnect with your VPN and check whether it’s working fine or not.
