Hello to all. I think its HW issue, or could it be OS issue?

Friend of mine brought me Lenovo Yoga 520 14IKB 80XB.
Current Windows are 1903 (18362.1082), I tried to update to 2004, but symptoms are the same, so I reverted back.

He has problem with WiFi.
Laptop sometimes see WiFi networks, sometimes not (the wiFi list is empty).
Sometimes after restart I can connect to the network, but after 20 seconds or so, it disconnects and there are no Wifi availiable in the list. In device manager, there is often yellow (!) mark on the device, I cant tell when or why.

In Widows logs, there is repeated error netwtw06 ID 5010.
I updated chipset and WiFi drivers from official Lenovo page, no success.

And here is the bombshell:
I physically removed WiFi module and I used ASUS USB Nano N10 adapter (I installed drivers before inserting USB dongle, as recommeded, as I always do) and still, it does not work. It still “does the same thing”, the symptoms are still the same. Its not working the same way 🙂

Any ideas or advices?

Interesting is, that it broke this january. Warranty ended on december 2020. Could it be coincidence?
I found several angry people complaining about lets say similar issues, but I want to hear some other opinions.

I think it must be some “general HW issue”, if the behavior is same with Wifi module removed and I installed USB Wifi. Whats your opinion, please?

Thank you for every note, or advice. I have very little experience with Lenovo.

Sounds like a software problem.

Reinstall Windows from scratch?

Sounds reasonable, I will make full backup with Acronis and ill try to reinstall. User has some data and Im not sure which ones to preserve.

The issue is repaired. I physically removed the wifi module, user can now connect to WiFi with USBdongle. Even after update built-in wifi was broken. I reinstalled 2004 from USB. I ran the setup directly from Windows, selected “Preserve only user files” and it took 30 minutes and now its funtional again. User files are still present, just few apps need to be reinstalled.
Interesting was, that Windows update downloaded Intel Display drivers and nVidia Display drivers simultaniously. But then it crashed with some unknown error.. Maybe the drivers are just downloaded and never used? Not suer about this.. But the rest of udates were successful, so the machine is up to date. Once again proved, that reinstalling is the best way. I tried built-in trouble shooting, which gave me information “Something went wrong..” so.. SFC / scannow showed error, but DISM could not repair it. Restoring was waste of time too.

Reinstaling Windows and remuving broken HW solved my problem.
