Windows 10: m.2 WiFi adapter not visible in Windows 10 Device Manager, but works in Linux

I have a Intel AX210 m.2 WiFi plus Bluetooth module that I was previously using on my Windows 10 Version 21H2, OS Build 19044.2006 PC without issues through a PCI-E to m.2 adapter. To free up the PCI-E port and the USB header, needed for Bluetooth, I tried installing the AX210 directly into my motherboard's m.2 WiFi slot it's an Asrock B550M Steel Legend on the latest beta BIOS L2.32.Now the situation is that the adapter is detected in Ubuntu just the WiFi and not the Bluetooth, but that's a separate issue, however in Windows, it's not detected at all. In Device Manager with Show Hidd

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

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?
