Windows 10: My wifi adapter just disappeared

This has happened twice..My wifi totally disappeared from my computer

:)

 

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 question

To be honest, I keep losing my wifi connection and Im almost positive its not due to my internet connection or Router or anything like that. VERY often, everyday, all day it keeps happening. The troubleshooter always resolves it by "reset wifi-adapter" (I believe this is the step it takes that resolves the problem) before it happens again anyways. Its driving me nuts ! Most time when it suddenly goes out (the connection) all the networks that should be in "show available networks" or all but the one I was connected to, disappear. I run the troubleshooter and it ends in resetting the wifi adapter. And it works. 10 minutes later, it happens again. Im trying to pin down the problem here. Thank you for your help.

 

Wifi adapter disappears after sleep

Thanks for replying.

@spirit MS MVP - This is the reason wifi is disabled when the computer goes into sleep mode. When I untick the "Allow computer to turn off the device to save power" and place the computer into sleep mode, the wifi adapter disappears. If i recheck it, and
put the computer to sleep, the wifi adapter does not get uninstalled.

@Andre - First solution does not work because the adapter does not exist and is not listed in the Device Manager.

Second solution doesnt work because the adapter is not listed in Troubleshooting. I tried troubleshooting all adapters and nothing was returned.

Third solution again does not work because the adapter is not there to uninstall.

The wireless driver/adapter disappears after restarting from sleep mode when the adapter's ""Allow computer to turn off device to save power" setting is unchecked.
