Well, I think I have found the solution. Reading the changelog from bcmwl source in Launchpad I see for the Bionic package:
https://launchpad.net/ubuntu/+source/bcmwl bcmwl (6.30.223.271+bdcom-0ubuntu4) bionic; urgency=medium * debian/dkms.conf.in, (LP: #1737744) debian/patches/0025-add-support-for-linux-4.14.patch: debian/patches/0026-add-support-for-linux-4.15.patch: - Add support for Linux 4.12. -- Marcelo Henrique Cerri <marcelo.ce...@canonical.com> Fri, 15 Dec 2017 18:22:18 +0000 This is available since mid December, well ahead of the hwe edge push to linux kernel 4.15. Looking at the bcmwl source changelog for building package bcmwl-kernel- source I don't see any support for kernel linux 4.15. So what all users need is a backport from the Bionic 18.04 package, waiting for this to happen as Seth Forshee suggested is plain non sense. If the packages are not up to date it's only an Ubuntu decision not to proceed with the update on depending packages. I will rebuild the package for Xenial in one of my PPAs and report back the result. >From the beginning I was suspecting that the kernel linux 4.15 patches were not applied, and it looks like it's the case. Now Xenial 16.04 LTS is supposed to get an extended support, so may be if updated with new linux kernels (availabe in official Ubuntu PPAs), Ubuntu should consider upgrading depending packages and this one bcmwl-kernel-source is clearly one. The same goes for the nVidia Graphics Drivers, which are still unsupported for Xenial 16.04 in linux kernel 4.15. I had to perform a rebuild of nvidia-390 with the appropriate patches for dkms to work properly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760108 Title: Broadcom B43 Wireless Driver Not Functional after Update to Linux Kernel 4.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1760108/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
