New computer setup wifi not working

I am trying to set up a new Lenovo IdeaCentre A540 Series all-in-one running Windows 10 Home. When it was walking through the initial setup, it detected several nearby WiFi networks. I had a problem getting the mouse connected and was not able to set the WiFi network. It was turned off and back on and then, upon getting back to that step, did not detect any WiFi. In Network and Internet settings it has no WiFi adapter listed and no WiFi options anywhere. I did make sure network discovery was turned on and I checked in Device Manager that the network adapter was enabled, but it doesn’t show up anywhere but in Device Manager.

Under Network Properties, it does list WiFi and says “Qualcomm Atheros QCA9377 Wireless Network Adapter”, status not present and connectivity disconnected. Under Device Manager I don’t see that adapter, it shows “Realtek PCle GbE Family Controller”, which appears to be the Ethernet adapter maybe? and a variety of WAN Miniports.

I’ve pretty much maxed out my knowledge here and I can’t find this exact issue when I search, so any advice would be much appreciated. Trying to help my stepdad set up to work from home during the pandemic...

Welp, now it's working. I realized I could show hidden devices in Device Manager, so I found the wireless adapter there. It was showing as not connected, so I shut down and dragged everything to another room and connected an ethernet cable, whereupon the wireless adapter started working perfectly. Maybe it was turning it off and back on the third time that worked, who knows...

 

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

Windows 10 21H1 and WiFi Adapter

dalchina, you're right in saying why not stay on the build that works; I am currently running 20H2 on the tablet. Personally, I like to keep my computers running on the latest version but I'll probably have to leave the tablet on 20H2 due to the WiFi. But it's just curious why 21H1 does not like the WiFi adapter. I've read about others upgrading and they find out after the upgrade that a component won't work, not before it actually starts. Normally, with components that are built to work on 8.1, I can usually find a fix or driver version that will work on Windows 10 and, there are a number of drivers that I found for the adapter that are specifically for Windows 10. Presumably, Microsoft have taken a different view of that adapter or 21H1 has been changed in some way.

In any case, thanks for your message and I'll probably do as you suggest.
