Power management tab is missing in device manager!

If i go to network adapters and open the properties of my wifi card (Intel(R) Wi-Fi 6 AX201 160MHz) there is no power management tab. Another post said to go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power in regedit, where I had to create a new DWORD called CsEnabled and set the value to 0, and restart, but that did not work. How do I fix this?

    Found the answer here:  https://www.reddit.com/r/Dell/comments/h0r56s/getting_back_s3_sleep_and_disabling_modern/

    Add PlatformAoAcOverride (0) to HKLM\System\CurrentControlSet\Control\Power; same place as the old CsEnabled key.

    reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

    Or to remove:  reg delete  "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride

    I can confirm this makes the Power Management tab available again for my Intel Wi-Fi 6 AX200 card!

    Same issue here.  Asus ZenBook Pro Duo laptop with Intel(R) Wi-Fi 6 AX200 card.  

    Tried the CsEnabled route.  Also tried the solution set out here:  https://docs.microsoft.com/en-us/troubleshoot/windows-client/networking/power-management-on-network-adapter#how-to-use-registry-editor-to-disable-network-adapter-power-management-on-a-single-computer

    But neither works.   The CsEnabled solution worked in Win10 1909 but not after 04 and certainly not in 20H2.  I have been reverting to 1909 as I need to be able to wake my laptop from Hibernate status.

    I have tried updating the AX200 driver directly from Intel and using the OEM produced for Asus.  Same result.  

    Both Intel and Asus passed the ball to each other on the driver but neither shows Power Management in 20H2.

    It's a Windows induced issue; please fix this.

    Thank you so much. This also solved my problem. The power management tab is back in the AX200 device properties on my laptop.

    Same problem over here: on an HP Spectre x360 15, no power management tab  (latest AX201 drivers)

    Suspecting that this is related to my issues with this wireless adapter - very slow wake from sleep, sometimes 5ghz band will not reconnect after wake (forcing a restart to resolve), and overall poor wifi speeds (about half the download speed I can get from my phone).

    I have the exact same issue here. Everywhere it says to create a registry key for CsEnabled = 0, but from my understanding this has no effect since version 2004. This is also what I am experiencing. We are on 20H2 here.

    Latest Intel WiFi driver doesn't solve the issue either. I'm fairly certain this is Windows issue as well.

    For the record I have the exact same WiFi adapter as the author.
