    Hello,

    If you wish to modify your Vista network interface MTU, I've just found that on the Internet.

    To check what MTU you have right now, enter in a command line (run as administrator) the following :
    netsh interface ipv4 show subinterfaces

    To set permanently a new MTU (e.g 1400), enter in a command line (run as administrator) the following :
    netsh interface ipv4 set subinterface "Local Area Connection" mtu=1400 store=persistent

    Just in case it could help.

    Regards,
    gkweb.

    Hi gkweb,
    This Microsoft article about the Vista "Auto-Tuning" feature might also help:
