WiFi Broadcom BCM43142 driver

Hello, I would like to report that the BCM 43142 Wi-Fi card on my laptop doesn't work.
I have the same issue with all other main Linux distros, although I was able to install the driver on arch with the `broadcom-wl` (or maybe `broadcom-wl-dkms`, I can't recall) package. On Debian based distros, I installed the `bcmwl-kernel-source` package.

I have no idea how to compile the OS from scratch with proprietary drivers, unluckily: could someone provide a general overview guide perhaps? I see that there are some patches for Broadcom devices, but to my understanding, they are for the ones supported by the kernel.

No repository files, tests, or entry points are named. Start by reviewing the existing Broadcom patches and the ChromiumOS build and driver documentation, then compare the BCM43142 requirements with the mentioned broadcom-wl and bcmwl-kernel-source packages. Done would require a confirmed support approach or a documented general build and installation guide.
