Windows 10: Cummulative Update KB4566782 wifi problem

I installed KB4566782 a few days ago. My system is Windows 10 2004, 64 bit, on Thinkpad T470.

As a consequence, I suffered from slow Wi-Fi surfing and VERY SLOW practically zero downloading speed.

After I tried every solution update drivers, etc. and checked that other devices in my home work fine, today I uninstalled KB4566782. The solution worked and now everything is fine again.

I learned my lesson: always better to pause updates for as long as possible...

KB4566782 Boot problem

KB4566782 update causing boot failure(black screen with dialer image). After several minutes, shut down and restart. After 2-3 restarts I got message "attempting repairs", and then "We removed some recently installed updates to recover your device from
a startup failure." Stopped updates to continue using computer for a few days and had no problems booting up. Downloaded update manually and installed and had same problem. Checked download list, KB4566782 not listed but KB45665503 was on download date. How
does this problem get corrected?

KB4566782 leads to AX200 WiFi driver error.

After installing KB4566782 and reboot, my AX200 WiFi driver was down.

Tried Reinstalling the driver, but fixes nothing. For now, I uninstalled the update patch, and my WiFi works again.
