Howto: Speed up your Network Connection on Windows Vista

Dana has a nice post on how to use netsh to tune network connection settings on Windows Vista. He reports that their downloads “went from 700Kbit download speeds to 18Mbit”.

First, launch an elevated command prompt by clicking Start, typing cmd in the search box, then hold down ctrl+shift and press enter.

To view your initial settings, type:

netsh interface tcp show global

Next, from an elevated command prompt type:

netsh interface tcp set global autotuning=disabled
netsh interface tcp set global chimney=disabled
netsh interface tcp set global rss=disabled

If you ever want to re-enable the original settings, from an elevated command prompt type:

netsh interface tcp set global autotuning=normal
netsh interface tcp set global chimney=enabled
netsh interface tcp set global rss=enabled

Note that for some strange reason autotuning=normal, while the other two settings=enabled
