Can anyone confirm that the following registry contains network card configurations?
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\DeviceNumber
I need to disable the options of letting the computer turn off the nic to save power.
I set
SavePowerNowEnabled = 0
Checked power management options of the card and it was still enabled, rebooted and checked but still shows enabled even though it's set to 0.
Also I found a post that setting PnPCapabilities to 24 stops the pc from turning off the nic.
When changing the checkboxes in the front end the value does change to 24. When I enable and set the value back to 0 and manually change it back to 24. The check boxes are still enabled even after a reboot. I really need it to show as disabled in the front end not just a trick that shows it enabled but doesn't actually put the nic to sleep.
Setting
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\DeviceNumber\PnPCapabilities
to 0x18 did the trick on reboot.
