Just installed Juno on a 2013 MacBook Air.

It's got a Broadcom 4360 wireless chip, which works great on the Live CD/USB, but the driver isn't there after install.

Is there a simple way to get wireless working on this device without having internet access?

when you boot from the install media, wifi works. so you could also reboot on the install media (cdrom, usb-key, or usb-hdd..) chroot into your installed system and then sudo apt install bcmwl-kernel-source. after that you can reboot, unplug install media, bcmwl-kernel-source will still be installed on your system, wifi will work normally.

to chroot, boot from the install media, open a terminal, mount your installed system on /media/target

$ sudo mkdir /media/target && mount /dev/sda2 /media/target
$ sudo mount ‐‐bind /dev /media/target/dev
$ sudo mount ‐‐bind /proc /media/target/proc
$ sudo mount ‐‐bind /sys /media/target/sys
$ sudo chroot /media/target
$ sudo apt install bcmwl-kernel-source

connect via ethernet and run update, the driver is included in it:

bcmwl-kernel-source Broadcom 802.11 Linux STA wireless driver source Version: 6.30.223.271+bdcom-0ubuntu1~1.3

You need to install bcmwl-kernel-source package somehow. Possible solutions are..

  1. If you have smartphone, share its connection via Bluetooth or USB, and install bcmwl-kernel-source package from AppCenter or sudo apt install bcmwl-kernel-source.

  2. Temporarily copy cdrom line on /etc/apt/sources.list in Live environment to your installed environment and sudo apt update && sudo apt install bcmwl-kernel-source
