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!

Jeremy

  • Which card, a BCM4306 or a BCM 4360? You refer to both. – ubfan1 Jan 13 '20 at 16:52
  • Please [edit] your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. – Pilot6 Jan 13 '20 at 16:54
  • I don't understand why do you ask me to edit the question ? Does something is missing ? thanks – Jeremy Jan 14 '20 at 09:19
  • it is the BCM4360 – Jeremy Jan 14 '20 at 09:21

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

  • There is no need to remove b43 firmware. There is no harm in it. And there is no need to install two packages. The correct one is bcmwl-kernel-source – Pilot6 Jan 13 '20 at 17:37

  • Don't you have internet at all on this machine currently? I mean no ethernet (via thunderbolt-rj45 adapter)? If so and you are trying to install offline, then get 'dkms' package as it is a dependency. Then do, sudo dpkg -i dkms_<version for 19.10>.deb and then, sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb. – svinoba Jan 15 '20 at 13:11

  • It means you have to download the kernel headers package as well and install it with dpkg command (dpkg -i linux-headers-<your_version>.deb). But then it may have other dependencies. It's better if you can get hold of an adapter (borrow if possible) or buy a wireless adapter that has linux support. I've a MacBookAir 11" and faced same issue as you. That is the reason I'm trying to answer even though the question has been 'closed' by others. In my case, I purchased thunderbolt-to-RJ45 dongle. Once, the driver was installed, the wireless works fine. – svinoba Jan 17 '20 at 17:57
