I thought this should be a simple plug & play operation, but I've now spent 5 hours troubleshooting it. Any help would be greatly appreciated.

After making the changes that you made (which you should have done - and stuck with - long ago, just saying), I suggest that you try doing a clean reinstallation of the driver stack - and yes, include both Bluetooth and Wireless.

Hope this helps,

It looks like it's not even secure boot related. I just went and disable secure boot, but left it uefi instead of back to csm as it was, and loaded back into windows, and wifi card still same issue. Went back into bios and switched uefi to csm, and wifi card works again once back in windows.

Did you try doing the clean reinstall?
