Bug description:
Specifically for Lunar - using a Macbook Air 2012, its wireless driver
was not enabled even though I ticked the wireless tickbox on the
installer.
A quick look at the installer logs reveals various issues
syslog:2023-03-29T18:01:25.141599+00:00 ubuntu-budgie kernel: [ 43.063747]

I will attach the installer logs manually since this was captured
after the installation
Note - on 20.04.6, 22.04.2 and 22.10 with the same laptop bcmwl was
installed correctly during the install so this is a regression with
the 6.2 kernel
Workaround
----------
You'll first need to blacklist the b43 driver by adding a blacklist file to
/etc/modprobe.d/b43.conf with the contents "blacklist b43". Then run
"update-initramfs -u". Then install the bcmwl-kernel-source package. After a
reboot your wireless device should be available.
