Windows 10: I am missing my wifi adapter after reinstalling windows.

So my computer was having some issues with the settings app disappearing after an update or two, but it fixed itself after I went back to a restore point would not let me uninstall update the three ways I tried. But then it happened again, and the restore point wouldn't work, because it claimed my computer was write protected, but diskcheck on CMD said it was not set to read only. So I went and reinstalled windows to a completely fresh installation, and the wifi doesn't show up. There is no wifi adapter driver on device manager, and when I tried to download a few and set them up, they still

Wifi adapter disappears - goes 'hidden'


Running Windows 10 on an Acer laptop. Over the past month, the wifi connection dropped without explanation/warning.

First time, the adapter was visible in Device Manager (with a yellow triangle next to it). An interent search found the suggestion to uninstall it and restart. That worked.

Today, the connection dropped again. In Device Manager at first I could not see the wifi adapter listed. I clicked to see hidden devices and found the adapter and the Bluetooth (which I had not noticed was missing).

I again uninstalled, restarted, and both the wifi and bluetooth have returned.

Anyone any ideas as to what is happening, why it's happening, and what I need to do, please?

I have attached a screenshot of the DM windows as it is now, showing the wifi adapter name, etc.

Thanks very much

Missing wifi adapter in windows 10

This is a screenshot of my device manager




I can't find the Intel WiFi drivers because I don't remember exactly what version I need and the automatic installer doesn't detect the adapters as missing.

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!!!
