MacBook 11,1 - WiFi driver broken after update

It appears that some updates that came through yesterday (3/30/2023) broke the WiFi driver on my Fedora 37 MacBook. I’ve tried various drivers for my wifi card (BCM4360) and unloading / loading the bcma, wl, and b43 drivers without success. I’ve also tried reinstalling the b43-fwcutter package as well as swapping this package for the open source b43-openfwwf package. I’ve also tried reinstalling the broadcom-wl but when I go to modprobe wl I get the following error message.
modprobe: FATAL: Module wl not found in directory /lib/modules/6.2.8-200.fc37.x86_64

I see that b43 is loaded but no device in use. From the lspci result it looks like my wifi card is using the bcma driver but I can’t seem to unload it with rmmod or uninstall it with dnf.

I had another laptop running Ubuntu 22.04 experience the same exact issue earlier this week but I was able to get that up and running by reinstalling the b43 firmware. This does not appear to be the case here.

Any advice is appreciated!

Thanks!

Check the output:

sudo dnf install broadcom-wl
rpm -q -a akmod-wl kmod-wl\*
rpm -V -a akmod-wl kmod-wl\*
rpm -q -l -a akmod-wl kmod-wl\*
ls -l /usr/src/akmods/wl-kmod*
sudo akmods --force --akmod wl
akmodsbuild /usr/src/akmods/wl-kmod.latest
sudo rpm --force -i ~/kmod-wl-*.rpm
sudo modprobe wl

If the issue persists, try this:

no or blank output for rpm -q -a akmod-wl kmod-wl\* , rpm -V -a akmod-wl kmod-wl\*, and rpm -q -l -a akmod-wl kmod-wl\*.

I’m pretty sure I uninstalled broadcom-wl package thinking it might conflict with the b43 driver.

sudo akmods --force --akmod wl

sudo modprobe wl

I assume I need to install the broadcom-wl package and re-run the above commands?

Doing so will install broadcom-wl and akmod-wl.

Installing the broadcom-wl, akmod-wl packages and then running the above commands again fixed it for me.

After a reboot, I’ve got my WiFi interface back and running!

Thanks @vgaetera for the quick response!

My wifi stopped working when i upgraded by MacbookPro8,2 from F36 to F38. This recipe fixed it. Thanks!

The output of the commands suggested that these packages were all installed and valid already. So i think it was just the akmodsbuild / rpm -i / modprobe bit that made the difference. This feels like something that should happen during the upgrade process. Is this an oversight in the tooling which does that? Could there be other kernel modules which need rebuilding too?
