Failed to install
To answer Paolo - the wireless device did show up and appeared to be
usable if I blacklisted bcma on the kernel commandline. Trying to use
'blacklist bcma' in modprobe.d/ did not work.
Steve had suggested that if the b43 driver is unusable, like an
unsupported PHY, that the module should not be
@Brian: by default, the b43 driver won't override the bcma driver
(unless you force it to, of course).
As for ubuntu-drivers, it does things correctly, meaning that it lists
the compatible proprietary driver (broadcom-sta-dkms), without
recommending its installation (over the open driver).
The
With the broadcom-sta-dkms package installed, can you blacklist bcma,
reboot, and see if wireless shows up?

I'm only seeing Modaliases for the broadcom-sta-dkms package (and not

1) On the firmware errors: they come from the open b43 driver, since the
firmware is not installed. This is something the b43-fwcutter package
can help with, if you want to use that.
2) As for the driver installation issue, I wonder if ubuntu-drivers is
confused, finding both bcmwl-kernel-source
I tested this same scenario on Ubuntu 22.04.2 and while I still don't
have a wireless device available I did discover the following:

After installing with the new desktop installer, rebooting, manually

Additionally, running 'ubuntu-drivers install' (before installing
broadcom-sta-dkms) indicated that all drivers were already installed.

Ok I'm sorry, this was a mistake on my part - I misread the PCI IDs in
the original log, or otherwise failed to line them up with what I was
seeing in modaliases. 14e4:4331 is indeed listed for bcmwl in all

The bcmwl driver SHOULD NOT have been installed on this hardware in

Marking this for broadcom-sta and linux-firmware.
If the restricted driver should be used but isn't, that's a broadcom-sta

If the in-kernel b43 driver should be used, then it's a linux-firmware
bug given the log entries about firmware loading.
