    Re: Changing MTU settings on Window 7

    Hello my friend,

    I think MTU(maximum transferrable unit) is the property of network not windows.
    You should change it according to the network connections.

    JUST follow these steps.


    1. Click Start, click Run, type regedit in the Open box, and then click OK.
    2. Locate and then click the following subkey in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\NdisWan\Parameters


    3. Add a Protocols
      subkey (if it does not already exist). To do so:
      1. On the Edit menu, point to New, and then click Key.
      2. Type Protocols, and then press ENTER.
    4. Add a 0
      (zero) subkey to the Protocols
      subkey. To do so:
      1. Click the Protocols
        subkey that you created step 3.
      2. On the Edit menu, point to New, and then click Key.
      3. Type 0 (zero), and then press ENTER.
    5. Click the 0
      subkey that you created in step 4.
    6. On the Edit menu, point to New, and then click DWORD Value.
    7. In the Value data box, type ProtocolType, and then click OK.
    8. On the Edit menu, click Modify.
    9. In the Value data box, type 800, make sure Hexadecimal is selected under Base, and then click OK.
    10. On the Edit menu, point to New, and then click DWORD Value.
    11. Type PPPProtocolType, and then press ENTER.
    12. On the Edit menu, click Modify.
    13. In the Value data box, type 21, make sure Hexadecimal is selected under Base, and then click OK.
    14. On the Edit menu, point to New, and then click DWORD Value.
    15. Type ProtocolMTU, and then press ENTER.
    16. On the Edit menu, click Modify.
    17. Under Base, click Decimal, type the MTU size that you want in the Value data box, and then click OK.
    18. Quit Registry Editor.
    19. Restart your computer.


    ALL THE BEST.

    Re: Changing MTU settings on Window 7

    The legendary tool, DrTCP, which is used by everybody to change the MTU in Windows 2000 and XP, doesn't work under Windows Vista. Fortunately, Microsoft now allows us to adjust the MTU using the "netsh" command. As other commands in Windows Vista, you run "netsh" using the command window, in Administrative mode.

    To see what interfaces you have on your computer, type

    netsh interface ipv4 show subinterfaces
    To change the MTU, type
    1.Netsh interface ipv4 set subinterface "Local Area Connection" mtu=nnnn store=persistent
    where.
    2.Local Area Connection is the name of the network connection on your computer, from the list obtained above.
    nnnn is the desired value for MTU.
    3.Reboot after making the change.

    All The Best!!!!!!!!!!!!

    Re: Changing MTU settings on Window 7

    Steps to change your MTU settings on windows 7:

    1)Open a command line window as an Administrator (ie. right click on All Programs > Accessories > Command Prompt and select Run as administrator) .

    2)Type the command netsh and wait for prompt

    3)Type the command interface and wait for prompt

    4)Type the command ipv4 and wait for prompt

    5)Type the command set subinterface "Local Area Connection" mtu=xxxx store=persistent

    ->Where “Local Area Connection” (including quotation marks as there is space in the name) is the name of the network connection on the computer, which is shown in the listing of network interfaces available. Common network connection name for Wi-Fi access is “Wireless Network Connection”.

    ->In addition, nnnn should be replaced with numeric value of the preferred size of MTU, with minimum of 576 for IPv4 and 1280 for IPv6. Note that if a value greater than the dynamically-determined MTU, the system uses the value of the dynamically-determined MTU instead. Thus, change of MTU is normally to reduce and reduce, but not to increase, the size of the MTU.

    ->If you want to change the MTU for ipv6 network interface, change the ipv4 in commands above to ipv6.

    6)After the change, reboot and restart the computer for the change to take effect.

    7)To verify the change of MTU has been successfully saved, use the following command:
    netsh int ip show int

    Re: Changing MTU settings on Window 7

    HI,


    TO CHANGE MTU SETTINGS THEY ARE AS FOLLOWS -

    1)To change or set a new MTU value, execute the following command:

    [FONT=Courier New]netsh interface ipv4 set subinterface "Local Area Connection" mtu=nnnn store=persistent[/FONT]
    Where “Local Area Connection” (including quotation marks as there is space in the name) is the name of the network connection on the computer, which is shown in the listing of network interfaces available. Common network connection name for Wi-Fi access is “Wireless Network Connection”.

    In addition, nnnn should be replaced with numeric value of the preferred size of MTU, with minimum of 576 for IPv4 and 1280 for IPv6. Note that if a value greater than the dynamically-determined MTU, the system uses the value of the dynamically-determined MTU instead. Thus, change of MTU is normally to reduce and reduce, but not to increase, the size of the MTU.

    If you want to change the MTU for ipv6 network interface, change the ipv4 in commands above to ipv6.
    After the change, reboot and [COLOR=#1FA2E1 !important]restart the computer for the change to take effect.[/COLOR]
    To verify the change of MTU has been successfully saved, use the following command:
    [FONT=Courier New]netsh int ip show int[/FONT]


    Which will return the response similar to the following:

    Idx Met MTU State Name--- ---------- ---------- ------------ --------------------------- 1 50 4294967295 connected Loopback Pseudo-Interface 1 12 20 1480 connected Wireless Network Connection 15 5 1500 disconnected Local Area ConnectionThe following command also works:
    netsh interface ipv4 show subinterfaces
