  1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip\parameters\\

    adding an MTU value.

Also tried netsh (in cmd) :

netsh interface ipv4 set subinterface "Local Area Connection" mtu=576 store=persistent

This question came from our site for professional and enthusiast programmers.

You can't set mtu in windows xp with netsh. Only the registry.

Here is a link to the KB Article for that;en-us;283165

You can also use a 3rd party program like Dr.TCP.
