Windows 10: In Device Manager my WLAN randomly changes to a triangle warning sign and I lose all WIFI...

In Device Manager my WLAN randomly changes to a triangle warning sign and I lose all WIFI connectivity. I am running Windows 11. I have updated, I have done a network rest. I have uninstalled the WLAN and still have the issue. It gives windows has stopped this device because it has reported problems code 43.

:)

 

Update made wifi adapter disapear

If the wifi adapter appears in Device manager without any warning triangle but there is no wifi section in Settings, Networks then reinstall the wifi adapter.

If the wifi adapter appears in Device manager without any warning triangle and there is a wifi section in Settings, Networks then use Settings, Update, Troubleshoot. I'd suggest this sequence:-
Hardware & devices
Network adapter
Internet connections

Best of luck,

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

Randomly losing internet connection on a wifi network

Is that ipv4 pool for DHCP? I usually set fixed IP addresses outside dynamic pool (so above .64 in your case)

Other solutions: like Superfly suggested, new wifi adapter (USB solutions in your case), and found one old HP thread... uninstalling HP hotkeys worked for someone - looks like app was messing with physical key...)
