** Description changed:
When I upgraded an older Macbook Air (running Ubuntu 18.04.4) from
kernel 4.15 to 5.5, the wifi adapter no longer worked. The system was
reporting that there were no wifi adapters found.
I did research, tried some of the suggested changes (mostly installing
the DEB package with the Broadcom kernel source) and had no luck getting
wifi to work.
Installed kernel 5.3.18 and the wifi adapter is found and is working.
cat /proc/version_signature returns 'no such file'
lscpi -vnvn returns (for the wifi adapter):
