Windows 10: AC1300 WiFi adapter stopped working after an update?

I had done an update a couple of days ago and now my Wi-Fi adapter does not work. The Bluetooth part works okay but the Wi-Fi part has completely disappeared. I have looked at Device Manager and System Information to try and resolve the issue but do now know where to go from there.

Wifi adapter has stopped working, wdiwifi.sys errors.

HP Envy 17t with Microsoft Windows 10 (64-Bit) with an Intel Wireless-AC 9560 160MHz network adapter.

My wireless network adapter stopped working on Tuesday. No Internet at all.

When checking the adapter properties I get the following status message:

Windows update log didn't show any updates this week, and I haven't installed any new software recently.

Troubleshooting steps I have taken:

• I have tried updating the driver
  
• I have tried disabling and enabling device.
  
• I have tried uninstalling and reinstalling drivers
  
• I have tried deleting device and scan for hardware changes.
  
• I tried rolling back, but that option wasn't available.
  
• I tried System restore (I only had one restore point and it was less than 24 hours old)
  

None of these worked.

I also ran FSC as admin in safe mode. It detected errors but couldn't fix them. The CBS log has multiple occurrences of "hashes for file member WdiWiFi.sys do not match."

I also tried installing a USB wifi adapter and got the exact same Code 37 error message.

I'm assuming WdiWifi.sys must be causing this but not sure.

Any suggestions on what to do next?

 

Wifi adapter randomly stops.

Hello!,

As the title suggests, my wifi card (Qualcomm Atheros QCA 9377) randomly stops working. It is showing a message on device manager saying something like "Windows has stopped this device because it has reported problems." This only started happening after
updating to Windows 10 1809 update. I can fix the problem by disabling and re-enabling the adapter but seriously, who wants doing that everytime it happens? Can someone give me suggestions on how to fix it permanently?

 

I keep losing my WiFi adapter

I tried the Option 2 approach but kept getting the Error NetSetupDeleteObjecton Network Adapter error (0x80070005) error, even after a dozen executions of the command. That seemed like it was going nowhere so I tried Option 1. After completing the reboot in Option 1, I never got the dialog that asked if I wanted to make the computer discoverable, even after a significant wait. Do you have any further suggestions? I'm going to move on to "Compumind's" suggestion in the meantime and see if that helps.... - - - Updated - - -

I started working my way down the list.

1. Both the ipv4 and ipv6 resets said "access denied!". However, the mere attempt worked *briefly*, then the WiFi went down again.
2. I disabled and re-enabled the network adapter. Again, it worked *briefly*, then I lost the WiFi again.
3. I tried to disable the antivirus but couldn't find a setting for that so uninstalled it entirely. I got the WiFi back and this time it stayed on for several hours instead of a few minutes so I assumed it was fixed. Then I installed the new Avast One and the WiFi is still working so I'm assuming that all is well finally!

Thank you for this list of suggestions!!!
