Re: Windows 7 TCP/IP tweaks - Tune your internet connection

I see you've already reverted back Matty, but for anyone else, the defaults on my Windows 7 Professional install were as follows:
Code:
Receive-Side Scaling State          : enabled
Chimney Offload State               : automatic
NetDMA State                        : enabled
Direct Cache Acess (DCA)            : disabled
Receive Window Auto-Tuning Level    : normal
Add-On Congestion Control Provider  : none
ECN Capability                      : disabled
RFC 1323 Timestamps                 : disabled

So the cmd file for reverting, in my case at least, would be as follows:
Code:
@echo off
echo Setting TCP/IP flags...
echo -----------------------
echo This only succeeds when run as an administrator,
echo when run as a user it only shows the current settings.
echo.
pause
echo.
netsh int tcp set global rss=enabled
netsh int tcp set global chimney=automatic
netsh int tcp set global netdma=enabled
netsh int tcp set global dca=disabled
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=none
netsh int tcp set global ecncapability=disabled
netsh int tcp set global timestamps=disabled
pause
cls
echo Current settings:
echo -----------------
netsh int tcp show global
pause
