How to install a Broadcom BCM4306 Wireless on MacBook Air [duplicate]

I installed Ubuntu 19.10 on my MacBook Air and I am not able to connect to the wifi.

I executed the to following command:

jb@jb-MacBookAir:~$ nmcli dev
DEVICE TYPE STATE CONNECTION
lo loopback unmanaged --
jb@jb-MacBookAir:~$ sudo lshw -C network *-network description: Network controller product: BCM4360 802.11ac Wireless Network Adapter vendor: Broadcom Inc. and subsidiaries physical id: 0 bus info: pci@0000:03:00.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=bcma-pci-bridge latency=0 resources: irq:18 memory:b0600000-b0607fff memory:b0400000-b05fffff

jb@jb-MacBookAir:~$

So as explained in "How do you get the Broadcom BCM4306 wireless card working?" I installed "b43-fwcutter" and "firmware-b43-installer" by following the following procedure:

"Téléchargez le pilote ici et sauvegardez-le sur un support externe, Copiez l'archive dans votre dossier personnel, Puis dans le dossier /lib/firmware/ avec la commande suivante que vous entrez dans un terminal: sudo cp broadcom-wl-5.100.138.tar.bz2 /lib/firmware/ Déplacez-vous dans le dossier /lib/firmware/ : cd /lib/firmware Décompressez-y votre archive avec les droits d'administration: sudo tar xfvj broadcom-wl-5.100.138.tar.bz2 Nettoyer votre dossier: sudo rm *.bz2 Redémarrez votre ordinateur."

Unfortunatly it didn't work. It is still saying 'No Wi-Fi Adapter Found".

Do you have any idea how to solve this problem ?

Thank you so much!

For your MBA, you need to install 'broadcom-sta-source' and 'broadcom-sta-dkms'. Remove all b43-* drivers you might have installed as they conflict with your card's drivers (if I remember correctly).

sudo apt install broadcom-sta-source broadcom-sta-dkms
