Public bug reported:
I have a bad branch kernel installed 5.12.5-051205-generic.... I need to get
rid of it and change to kernel version 5.11.0-43-generic.
However, I have no WiFi hardware detected when booted into 5.11 kernel from
grub menu.
I can ONLY get my WiFi hardware to detect in kernel 5.12
I only have network access through ethernet cable while booted into kernel 5.11
