Intel WiFi 8265

[Mrmcreynolds]

Intel WiFi 8265 works when I install Windows. When I install Kubuntu, not dual boot, the WiFi is not loaded. The drivers are there but cannot see any networks.

Posting the error msgs would be helpful, if any are displayed. Or, do dmesg or "journalctl -b" to see the latest error msgs, if any.
Meanwhile, maybe this will help:

Maybe the wrong wifi is trying to load https://h30434.www3.hp.com/t5/Notebo...4/td-p/6365594 but we are just guessing without seeing the errors

I am not dual booting. when I install Win10 or Win11, it works as expected. I have tried ubuntu 21.04, 21.10 and kubuntu 21.04, 21.10 and even Fedora 34 and 35.

Indeed! On Windows and several Linux distros.

Kc2di recommended trying rfkill. With it you can see if the card is blocked, and if it is perhaps unblock it using
rfkill unblock wlan (or what ever your wifi device is named)
