I have a HP ProBook 6570b as my work machine and while installing Cinnamon and Fedora 24 I found myself challenged to get WiFi working with the Broadcom WiFi adapter.
How did I solve it? Well, there were two likely methods that really are the same method, installing the WiFi drivers from the HP Support Site, however, they require a few additional dependencies, notably gcc and the kernel-devel packages. And the instructions weren’t provided. Just as I was determining what it was missing I happened across this command:
wget http://git.io/vuLC7 -v -O fedora23_broadcom_wl_install.sh && sh ./fedora23_broadcom_wl_install.sh;
The details of which are located here on a site which some browsers may not like as the site isn’t configured correctly. Still, the script is available and easily understood from the documentation.
The best part is I now have WiFi and it wasn’t so bad after all.
