Windows 10: Stop Turning Off Wi-fi in Sleep Mode

It started with the update to 11. It takes minutes to get the wi-fi running again from sleep mode, nevermind how urgently I need to connect. All advice online says to find the power management tab in the device manager but there is no such tab. Fix this?

Wi-Fi Connection After Sleep Mode

When the computer wakens from sleep mode it connects to Wi-Fi, although "Settings" shows that "Connect automatically when in range" is off. I must turn the Wi-Fi connect off manually.

 

Losing Wi-Fi AFTER Sleep

I noticed there are WDKs for 1903 and 2004 yet none listed for 1909 (which apparently you use).

I suppose you could try scripting turning Airplane Mode on then off again to see if it will force a re-scan of the Wi-Fi card (I think it uses WUDFHost.exe). Brink did this using compiled AutoIt scripts for Windows 8.

Alternatively, have a look at powercfg.exe and, in particular, check the sub-group GUID for Wireless Adapter Settings:




With this in mind, and going back to your first post, the pivot point seems to be how consistently your Wi-Fi adapter is successfully enumerated after a sleep state. AFAIK only something like traces using the WHLK or WPA can determine this. Microsoft's advice is:

I suggested the use of devcon.exe as it can force a re-query of hardware, i.e. it's possible to script the equivalent of 'Scan for hardware changes' in Device Manager's GUI... so at a completely different (ACPI and/or PnP) level to network/Wi-Fi settings after hardware is initialised and identified.

I've found several posts where devcon.exe was used or suggested for similar hardware resume issues.

EDIT: Ignore my powercfg.exe suggestion. On re-reading, you've already tried this.

 

Windows 10 --- Airplane Mode Will Not Turn Off / Wi-Fi will not turn on

For 3 months I have had the same agonizing problem with wi-fi since upgrading from 8.1 to 10 but I believe I have found the solution! First connect to the internet via ethernet.You may want to try just disabling or uninstalling the airplane mode
switch in the Human Interface Device first.Since I have a Dell laptop I went to Dell.com support did the diagnostic and received a service tag number after that scroll to drivers & downloads, choose the find it myself tab. Notice the list of
driver updates. Before you do any of the updates google or bing (order of driver installation). This list the order in which to download and install the drivers. After this is done you
may still have go in device manager under Human Interface Devices and disable the airplane mode switch or uninsatll it. I uninstalled mine. It showed back in after a reboot but I haven't had any issues with wi-fi connection since. My airplane mode can't turn
on now but my wi-fi is working fine. Yippee! That was the long way around. You may want to try just disabling or uninstalling the airplane mode switch in the Human Interface Device first.
