Disable “Allow the computer to turn off the device to save power” for all WiFi adapters

Written by Ingmar Verheij on May 1st, 2014. Posted in Other

When a Windows computer enters sleep mode it ensures that WiFi adapters enters the device power state D3 (Sleep) and on resume ensure it puts it back to the device power state D0 (Full on).

Windows assumes that if a driver says it supports sleep states it handles this correctly, but this setting is known to cause some spontaneous disconnects with the access point (AP). Optionally Windows can be configured to place the WiFi adapters in device power state D4 (Off).

I wrote a PowerShell script that disables the “Allow the computer to turn off this device to save power” setting for all WiFi adapters.

Update 26/10/2017: Included an option to disable for all network adapters.
