Changing the MTU size in Windows PC

Hi guys, one day we need to check the bandwidth of the leased internet link provided by ISP. we continuously checked 4 days but is not reached required amount of bandwidth. then as per the ISP suggestion we changed the MTU size from default 1500 to 9200 bytes. after this changes we reach the maximum bandwidth with use of Solar wind Wan Killer.

Once the Command Prompt window is open follow the steps below to change the MTU size:

  1. Type netsh interface ipv4 show subinterface
  2. Press Enter.


  1. You will see a list of network interfaces.
  2. Type netsh interface ipv4 set subinterface “Local Area Connection” mtu=1458 store=persistent
    You should replace Local Area Connection with the name that appeared in the “Interface” column from steps 1-3.
  3. Press Enter.
  4. Restart you computer and then test again.

The PC is set the MTU size as per your request. now you can push the more amount of data to the network.

don't try to set in working environment, it will affect the internal network,
