Windows 10: My wifi adapter is completely gone after I reinstalled windows

I reinstalled Windows and laptop was working completely fine, I opened it again and the wifi option was missing, I looked into the device manager and it's gone, I checked hidden and it won't show up, only asks for Ethernet but I've never used Ethernet before, I decided to reinstall windows again but it's stuck in the blue page that says "Let's connect you to a network" and it's completely blank :

I keep losing my WiFi adapter

I tried the Option 2 approach but kept getting the Error NetSetupDeleteObjecton Network Adapter error (0x80070005) error, even after a dozen executions of the command. That seemed like it was going nowhere so I tried Option 1. After completing the reboot in Option 1, I never got the dialog that asked if I wanted to make the computer discoverable, even after a significant wait. Do you have any further suggestions? I'm going to move on to "Compumind's" suggestion in the meantime and see if that helps.... - - - Updated - - -

I started working my way down the list.

1. Both the ipv4 and ipv6 resets said "access denied!". However, the mere attempt worked *briefly*, then the WiFi went down again.
2. I disabled and re-enabled the network adapter. Again, it worked *briefly*, then I lost the WiFi again.
3. I tried to disable the antivirus but couldn't find a setting for that so uninstalled it entirely. I got the WiFi back and this time it stayed on for several hours instead of a few minutes so I assumed it was fixed. Then I installed the new Avast One and the WiFi is still working so I'm assuming that all is well finally!

Thank you for this list of suggestions!!!

 

Help, WiFi adapter completely gone

The WiFi option on my laptop disappeared. I used network reset, still gone. Ran some code in terminal, still gone. Reset my laptop, still gone. In device manager under network adapters, my wifi network isn’t there either. When I troubleshooted I quote, it told me “You’re connected using a virtual network adapter that we can’t test.” Even though I’m not connected to anything. What do I do now

 

Wifi adapter completely disappeared, not listed in Device Manager

I'm asking this question not for myself but for anyone who might run into the same problem as me in the future, to save them a lot of time and possibly panic.

I had a BSOD (an undiagnosed graphics issue that is triggered by Skype conference calls). When I rebooted, my wifi adapter had completely disappeared (a Qualcomm Atheros QCA61x4A; the computer is a Lenovo Yoga 710-14IKB). The network troubleshooter couldn't bring it back and it had completely disappeared from Device Manager. I plugged in an ethernet adapter and tried downloading and twice reinstalling the driver and then rebooting, but that didn't work. I ran "DISM /Online /Cleanup-Image /RestoreHealth" and then "sfc /scannow" in an adminstrator PowerShell, but still no joy. I then booted into MX Linux from a USB stick, but that couldn't see the wireless adapter either. By this point I was convinced that the BSOD had killed the wireless adapter hardware, but I tried one more thing. I rebooted into the UEFI settings and looked to see whether the adapter was listed as enabled there. Apparently it was, so I changed nothing and then selected "save and exit". When Windows started up again, the adapter was working. I then tried rebooting into MX Linux and the adapter was working there too.

Which of the steps I took is most likely to have resolved the problem? Was it when I opened the UEFI settings and saved them without changing them?
