Windows 10: Cumulative update 2021-03 KB5000808 causes Wireless Adaptor stop Code 43

Cumulative update 2021-03 KB5000808 for 1909 X64 installed automatically on 11/03/21. Since then my Wireless adaptor, Qualcom Atheros QCA9377, has been stopped Code 43.


I can not uninstall 2021-03.


I know there there is a compatibility issue with this adaptor, as Feature update 2004 is held, on my laptop, pending resolution. This is confirmed on MS information pages.


It would appear a fix included in 2021-03 has caused the problem.


Trying to reinstall the driver Driver Date 222/08/18, Version 12.0.0.722 does not work, as it only looks for the latest, which leads me to believe 2021- 03 has not updated the driver.


Therefore, there must be another underlying problem, also in Feature Update 2004.


I also find Cumulative update 2021-01 KB4589211 is also waiting to be installed. 2021-02 already installed.


Any ideas or preferably a solution, please.

Mike.

Code 43: Wireless network adapter

I followed a previous suggestion. This I had already done prior to reading the suggestion. Basically I

get error 43 on my network adaptor and have lost all wireless connectivity.

How can I get this back.

I am running windows 10 on my pc with that so called free update from Microsoft.

I will not go into all the other problems I have had, but loosing my wireless is the last straw.

If it is a windows 10 problems I will not bother fixing it, if pos. I will just bin the PC.

Please someone help.
