On both Ubuntu and Ubuntu Gnome, I have working wifi in the installer, but not after. There is no wireless device in the network settings, and I've tried the following with no luck:

WIfi Issues with Macbook Pro Retina Early 2015 (12,2) on Ubuntu 15.04

wifi problem on MacBook pro early 2015 running Ubuntu LTS 16.04

Here are some details:

Edit: It seems Ubuntu is incorrectly treating the adapter as wired on every reboot. Closing and re-opening the lid seems to temporarily fix it for whatever reason.


After a "fresh" installation of Ubuntu 16.04, the driver for my wifi hardware Broadcom Corporation bcm4322 was not detecting any wifi networks in my MacBook Pro (Core 2-Duo from 2010).

Fortunately, while being connected through wired Ethernet I found a work around:

  • go to System Settings | Software & Updates, then pick the Additional Drivers tab.
  • There was a section "Broadcom Corporation: BCM4322 802.11 a/b/g/n wireless LAN Controller" with an UNSELECTED radio button labeled "Using Broadcom 802.11 wireless driver source from bcmwl-kernel-source (proprietary)" and also a SELECTED radio button labeled "Do not use the device". The only thing I did is clicked the former UNSELECTED radio button and within a few minutes it got the wifi connections worked perfectly
