Wifi Keeps Shutting off

[Balashiguy]

My Wifi keeps shutting off when I put it into sleep mode or close the laptop. I am forced to restart every time in order to reconnect. I have watched videos that reference a "power management" tab, but it does not exist where it should. Need

Possibly the problem is fast start which uses the hibernate file.  The hibernate file may have been created when Wi-Fi was disabled or sleeping.  Ever time your system starts up using the hibernate file the Wi-Fi is then turned off.

Make sure the Wi-Fi is working and then create a new hibernate file 

To get a new hibernation file do the following. Enter 'CMD' in the windows search and select 'run as administrator'.
Be sure to close other apps to avoid losing data during the hibernation.

powercfg -h off
powercfg -h on
shutdown /h

Make sure your system is working correctly. If a device is not working when you create the hibernation file, that device will be marked as not working every time your system resumes. This will be true even if the device is fixed.

If the above does not help then you need to disable moderns standby.  The power management setting is not available on any system running modern standby.

Modern standby is explained here

If you are using Modern Standby then your bios is configured to use S0.

Please copy and paste the following command into Windows Command Prompt using Administrator mode.

powercfg /a

Should look something like this:

If there is a problem with modern standby possibly your BIOS setup has the option to use S3 instead of S0.

If not, then this article explains how to disable it. If you decide to try disabling using any of the methods explained, be sure to set a restore point in Windows to make it easy to return to s0 state.

Disable modern standby with :

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

Windows sleep diagnostics are shown here
Try running those diagnostics first.
Let me know what you find out.
