WiFi driver stopped working after windows update (OS: Windows 10)

Hey guys!

So a couple of days ago my WiFi stopped working. All WiFi-related menus simply doesn't show up anymore. Seeing as i use ethernet when at home, i'm not quite sure when this happened, but i presume that it was after a windows update i did a couple of days ago.

So i went into Device Manager and checked out my WiFi-adapter and sure enough, it had a little yellow triangle next to it.

So i tried updating the drivers, disabling/enabling the device, reinstalling the device (with reboot of system) and all of that. Nothing works.
Under Properties/General/Devide status it says "Windows is still setting up the class configuration for this device. (Code 56)".
I then tried downloading the driver off the Acer support site (I supplied the correct SNID, so model should not be the problem). When i try to install that as the driver from the device manager, it takes forever, and eventually results in a timeout.

I've been googling possible solutions for the last couple of hours with no result.

I already tried:
 - Uninstalling VPNs (i don't have any)
 - running sfc /scannow


Any suggestions on what to do would be very much appreciated!

Cheers,

Mathias.

  • First uninstall and delete the network driver in the device manager and then restart the notebook:

    Then install this driver and restart the notebook using the .inf file from the device manager: https://www.ath-drivers.eu/qualcomm-atheros-download-drivers-nr-355-with-code-4043.html
    I recommend that you turn on system protection! If it does not work, restore windows to a point in time before the problem!

    Thanks for the quick response!

    Exactly how do you mean install using the .inf-file?

    What i tried:
     - Right clicking the adapter in device manage -> update driver -> Browse my computer for driver software -> (and then i browed to the folder containing the .inf-file)

    Is that what you meant?

    Update: This just caused a timeout error after trying to install for about 3 minutes.
  • I recommend that you restore the notebook here:

    however make a backup of your files before restoring windows!

    Restoring actually helped, even though it's never a nice road to go down :)
    Thanks for the help, and i hope other people might find this useful as well :)

    Better get back to installing all my programs again though!

    Cheers! :)

    having the same issue but I just got my helios 300. 
  • Have you tried upgrading windows and drivers? Did you check if disabling fast start up in power options solves the problem?
