BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] Not consistently working

Asked by Max Wei

I have installed Ubuntu 18.04 LTS onto my old Macbook Pro (MId-2010) and can not get the WiFi to work. The WiFI would not detect anything at times. I am noticing that the WiFi seems to work flawlessly when at home, even after rebooting and hibernating the Macbook Pro multiple times. However, once I bring my Macbook Pro to work with me and bring it back from hibernation state, the WiFi would not detect anything although there are networks around. The WiFi did detect several networks while at work once and then I could never get the WIFi to work properly again since then. I also have a Verizon MiFi with me that I was planning to connect and it would not detect it at work, it does detect the MiFi at home though. Please advise.

Info above was pulled/generated when I was at work earlier today, when the WiFi would not pick up any networks. Verizon MiFi Jetpack was active and my phone was connected to the MiFi with no issues.

Open terminal and do

sudo apt update && sudo apt install bcmwl-kernel-source

Then reboot

I did have the bcmwl-kernel-source installed before but saw that other users, that have the same network card as me, were recommended/instructed to install/use the firmware-b43-installer instead so I followed those footsteps to more success compared to when I was still trying to debug around with the bcmwl-kernel-source.

More info on what I attempted to do already to prevent going around in circles (haha):

Also, this morning from the office...looks like everything is actually up and running OK this time but still not detecting my Verizon MiFi Jetpack that is next to me. The dmesg looks much much cleaner compared to when I ran dmesg yesterday when I got into work so still am super confused on what is going on, lol

I purged firmware-b43-installer and installed bcmwl-kernel-source just for shits and giggles and this is the result:

Did some more playing around with firmware-b43-installer after removing bcmwl-kernel-source again! I managed to get the WiFi to detect the wireless networks at work again by doing the following:

$sudo modprobe -r b43
$sudo modprobe b43
$sudo service network-manager restart

The thing is...the WiFi finally detects the network but CANNOT connect to anything at all.....following is the dmesg:

I installed Ubuntu 18.04 LTS onto my old Macbook Pro (Mid-2010) too ;)
I had some problems with wifi too.

So here is my answer :

# sudo apt-get purge bcmwl-kernel-source firmware-b43legacy-installer firmware-b43-installer
# sudo apt install firmware-b43-installer
# reboot

# sudo modprobe -r b43 bcma wl
# sudo modprobe b43 pio=0 qos=0

And now the wifi works, in PIO mode, not DMA, but at least it works !
Hope it helps, feel free to ask details.

Can you help with this problem?
