I have a macbook air (2015, Model A1465). The chipset is BCM4360:

I use rEFInd to boot into Ubuntu 18.04, no problems during install execpt for no wifi. I hotspoted and installed the broadcom-sta-dkms drivers. Everyhthing goes smoothly, and when I restart wifi works.

When I restart the machine, I lose wifi.

I downloaded the broadcom package: broadcom-sta-dkms_6.30.223.271-8_all.deb and ran:

sudo apt install --reinstall broadcom-sta-dkms

getting the following output:

sudo apt install --reinstall broadcom-sta-dkms

rEFInd tries to boot into the .old-dkms image by default. So I enter into single user mode and boot from the new initrd.img-4.15.1-041501-generic.

The wifi works again, until I reboot. And so the cycle repeats!!

I've tried many things, including blacklisting every other driver/package that could be interfering, but nothing works. Here's list I have so far /etc/modprobe.d/blacklist.conf:

blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
blacklist b43-fwcutter
blacklist bcm43
blacklist bcm43xx
blacklist ndiswrapper

Executing:

sudo modprobe wl

makes no difference

Similar questions have been asked previously, but don't really address my particular issue

TL;DR: I lose wifi every time I restart. What should I do?

This worked for me.

wget http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb
sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb

This is the source: BCM4360 802.11ac not working w/ 4.15.0-29-lowlatency recent update.
