Broadcom wireless driver [14e4:4328] (rev 05) on Ubuntu 18.04

Second update: It was too good to be true. I installed hplip, which required a reboot. After the reboot, the card no longer sees any ssid. Another reboot does not help. I also used ifconfig to shut down and restart the driver, but no love. I also found this post from a couple of years ago: Wifi connectivity for same card. It was also answered by Pilot6, but a comment at the bottom shows that at least one person had the same problems I have, that it is does not work after reboot.

UPDATE: @Pilot6 requested more information, which I provided. I did yet another reboot, and that seems to have done the trick, for some reason. I did not try anything else to fix the problem (except read about it). Apparently, a third reboot was all that was necessary. It seems to be working now. If there are stability problems, I will report back here. Otherwise, this chip could be added to the list with the right fix.

I just installed Ubuntu 18.04 on an old macbook air with core 2 duo. The wireless card works, but is not seen by the new os at all. Thanks for the attention to the problem, @Pilot6!

I have read through the (excellent) instructions on getting these cards working on linux. There is an extensive list for different cards, but not this particular revision. So, I followed the recommendations and did the following:

sudo apt update
sudo apt upgrade
sudo apt-get purge bcmwl-kernel-source
sudo update-pciids
sudo apt install firmware-b43-installer

Then rebooted. This allows the OS to see the card, but the card could not find any networks. So, I also tried

sudo modprobe -r b43
sudo modprobe b43
sudo rfkill unblock all

I could detect no change in behavior, however. Linux still sees the card, but the card sees no networks.

Per the request below:

lspci -knn | grep Net -A3; rfkill list

I have [14e4:4328] (rev 05) on Ubuntu 18.04 and my issue was that I could see wireless networks but could not connect to them (error message "activation of network connection failed").

I was able to resolve it with just the below steps:

sudo apt update
sudo apt upgrade
sudo apt-get purge bcmwl-kernel-source
sudo update-pciids
sudo apt install firmware-b43-installer
reboot
