Missing wireless network interface after kernal 5.3.0-43 upgrade with eoan

Asked by Rustin Schenk on 2020-03-21

I updated to latest kernel: initrd.img-5.3.0-43-generic and find that my network is in airplane mode. ifconfig shows there is no wireless interface setup. When I go back to kernel 5.3.0-42 everything is working correctly. I am using an HP laptop.
I can see the wireless network controller with lshw:
