Just a comment on your last guess: The output I posted was really the output from lspci. I noticed as well this was not the output I get on other kernels for this command. However on other kernels all pci are claimed so the unclaimed status of one pci may explain the different output.
Definitely there is something wrong with kernel 4.15. Next thing I will try is purging and re-installing bcmwl-kernel-source package within kernel 4.15, as I installed it in kernel 4.13. I realized as well that package broadcom-sta-dkms was not installed and may have impaired the dkms update. I installed it yesterday along with broadcom-sta-source broadcom-sta-common. When installing a new kernel this source is used to build the new dkms wl module. However there is nochange and I still get the dkms error when installing 4.15. -- 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 email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
