This topic is part of the WDI driver model released in Windows 10. The WDI driver model is in maintenance mode and will only receive high priority fixes. WiFiCx is the Wi-Fi driver model released in Windows 11. We recommend that you use WiFiCx to take advantage of the latest features.
OID_WDI_GET_AUTO_POWER_SAVE gets the power save state of the port.

There is a trade-off between power saving and latency. When auto power save mode is set to be enabled with the OID_WDI_SET_CONNECTION_QUALITY command, the firmware tries to interact with the connected access point to go to power save mode as much as appropriate to save power. The firmware is also responsible for detecting if the connected access point confirms to the 802.11 specification and follows the power save mode protocol. If the access point does not conform (does not support power save mode correctly), the firmware should not go into power save mode, even when Auto Power Save is set to enabled. When Auto Power Save is set to disabled, the firmware focuses on low latency of sending and receiving packets. Examples of this are when streaming mode is on, and when the system is using AC power so low latency is preferred to saving power.
