Hi.

I'm redirected here from bug #1770029

When upgrading kernel to 4.15.0-24-generic I also had problem with my broadcom network card : lost wifi

So I try to reinstall broadcom-sta-dkms :

:~$ sudo apt-get install broadcom-sta-dkms 
[...]

Consult /var/lib/dkms/broadcom-sta/6.30.223.271/build/make.log for more information.


And then I take a look to the make.log file :

~$ cat /var/lib/dkms/broadcom-sta/6.30.223.271/build/make.log
