Windows 10: Wi-Fi Doesn't Work After Sleep Mode

This issue happened recently after an update.I use Windows 11 Home. Version 10.0.22621 build 22621When I wake up the PC after it sleeps, the Wi-Fi is off. Only by restarting or doing a network adapter troubleshooting does it come on again. Also, the computer screen is very dimmed, even if the brightness is all the way up. That's only fixed by restarting the computer. This issue also happens when I unplug the computer and use battery mode.

Hi Rajan,

Thank you for posting in Microsoft Community.

I suggest you to run the below troubleshooter and check.

Note:

Airplane mode is a setting that gives you a quick way to turn off all wireless communication that are already enabled on your PC. Once you turn on Airplane mode, you can turn an individual Wi-Fi connection ON even in Airplane mode. This disable all other
connection except the enabled Wi-Fi connection. This is not a bug/problem as this was also available in Windows 8.1. I suggest you to refer
To turn on individual wireless devices while airplane mode is on
section in below given link:
