Change Autotuning, RSS, Chimney and Taskoffload Settings

To get the status of you present settings open an administrative command prompt and run:
netsh int tcp show global
netsh int ip show global

There are 4 settings that are regularly changed to tune performance for older clients, to disable them you would run the following commands:

netsh int tcp set global autotuning=disabled
netsh int tcp set global rss=disabled
netsh int tcp set global chimney=disabled
netsh int ip set global taskoffload=disabled

Finally you must reboot the appliance.
