Hello all. I am unable to disable the "Reduce link speed to save power" and "Reduce link speed during standby" options under the Power Management tab, in the Intel 82566DC Gigabit Network Connection Properties. This occurs in Windows XP Professional x64 Edition (SP2) with Intel PROSet Version: 188.8.131.52. I cannot disable these settings either in OS Normal or Safe Mode. Is this by design?
On the same computer, I also have Windows XP Home Edition (SP3) installed on a different partition. Under this setup, the Intel PROSet version is older, but I am able to disable and enable the same applicable power settings.
Thank you all for your helpful and timely responses.
