hi autriche2006_2021,
I also had those same errors so I removed all Intel WiFi drivers by the device manager by the following.
In the device manager keep deleting the Intel WiFi drivers ticking attempt to remove the driver for this device, I had to remove 6 sets of drivers, once all are removed the device manager shouldn't list the Intel Wi-Fi. then reboot and install the latest WiFi drivers, I used another computer to download them, then tranfered by USB stick. I clicked on the wifi driver install program , once installed rebooted, back to Windows and then the wifi card showed up, entered user name and password and haven't had a problem since, I have even installed the latest Dev last night without problems.
