Solved how to permanently change mtu?

[jmm]

hi, anyone can tell me how to permanently change the mtu for a given network device in win7? the cmd "netsh interface ipv4 set subinterface “NameOfConnection” mtu=XXXX store=persistent" does not work for me: mtu value goes back to initial after reboot...
thank you

hi,
you can modify the windows registry for this as well.

click start type regedit the navigate to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\[Adapter ID]]

(Find the correct adapter you want to change on your machine, there may be multiple entries depending on the number of adopters you may have)

the right click and create a new REG_DWORD, name it MTU, set the value after that.

hope this helps

Cheers !!
