So this time it looks like the network adapter is recognized by the
kernel 4.16 (it was UNCLAIMED by kernel 4.15).
Both the Wi-Fi network adapter and Bluetooth are recognized. However,
Ubuntu System Settings does not see any Wi-Fi ... So it can't connect
through anything Wi-Fi ...
It looks like there is definitely a bug in kernel 4.15.0, although I
don't know why Ubuntu can't see the recognized Wi-Fi network adapter in
kernel 4.16.0.
How can we label this bug then ? Is it considered kernel-fixed-upstream
? though there is no Wi-Fi recognized by Ubuntu Xenial 16.04 ?

Title:
Broadcom B43 Wireless Driver Not Functional after Update to Linux
Kernel 4.15
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Bionic:
Incomplete
Bug description:
I was upgrading my Ubuntu Xenial 16.04 from linux-hwe kernel 4.13.0-38
to linux-hwe-edge 4.15.0-13.
After reboot my Broadcom network adapter (requiring package
firmware-b43-installer) is not recognized by the new kernel 4.15.0-13.
Running the lspci command lists the device as 'UNCLAIMED' in linux
kernel 4.15.

The circumstances of this bug is well described on this webpage:
https://bbs.archlinux.org/viewtopic.php?id=234122
Furthermore a patch has been provided upstream:
[UPDATE]: This patch is already part of the used kernel version.
Hence this bug is not related to this patch.
https://patchwork.kernel.org/patch/10185397/
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers.git/commit/?id=a9e6d44ddeccd3522670e641f1ed9b068e746ff7
But is still not implemented in any Ubuntu release.
If this is not corrected on time, then the new Bionic 18.04 will fail to
connect to Internet and the local network as well if it uses a Broadcom network
adapter requiring the package firmware-b43-installer.
