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] b43 bcma0:1: Direct firmware load for b43/ucode29_mimo.fw failed with error -2
  syslog:2023-03-29T18:01:25.141625+00:00 ubuntu-budgie kernel: [   43.063802] b43 bcma0:1: Direct firmware load for b43/ucode29_mimo.fw failed with error -2

  syslog:2023-03-29T18:01:25.141626+00:00 ubuntu-budgie kernel: [   43.063908] b43 bcma0:1: Direct firmware load for b43-open/ucode29_mimo.fw failed with error -2

  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.
