Wi-Fi Not Working

The Lenovo Xiaoxin notebook installs the official website wifi driver, and it can be used normally.

After tens of minutes, it will not be able to connect to the wifi

Check the device manager and find that the wifi driver has an exclamation mark,

indicating that there is a problem with the device, and windows has stopped it, code 43

The WiFi adapter is Qualcomm Atheros communications Inc

Later, I looked at the driver again, the wifi driver disappeared

Click to view hidden drivers, a microsoft Kernel debug network adapter appears

How to solve this

thank you for your help

Hi, if you examine your Windows Update History, down at the bottom, or perhaps your Device Manager driver, is there any sign of having received an update for that driver?

How do you get it working again- do you reinstall the driver from the manufacturer's website?
Or does it start working again after a restart, for example?

History: (most posters never give this)
- when did this start happening?
- what is different between now and the last time this did not happen?

What security software are you using?

Please create a new user for test purposes.
Log in as that user. Does the same thing happen?

Your laptop (from your specs): Lenovo Thinkpad X200s is from around 2009 - very old. Is that the one you're asking about?

As such there are no guarantees whatsoever of it working successfully with Win 10.
If it was supplied then with a 32 bit O/S and driver support and you have now upgraded to a 64 bit O/S for example, you may indeed expect problems.

thank you for your reply

This computer is my client’s lenovo xiaoxin laptop

I directly downloaded the official Microsoft image, clicked on the ISO image in the system, and ran the setup to reinstall the system

After entering the desktop, there is still no wireless adapter in the device manager

What's the reason？

Is the driver signed if not it can load then be removed by MS

The problem with the computer now is that it can’t find the wireless network adapter at all.

I suspect wifi device failure. You may try running the Hardware Troubleshooter to diagnose the issue better.
