There's lots of people/places talking about how to get this card to function.
None of it works for me.

Most of it, has been along the lines of grabbing some broadcom stuff off a repo, then your drivers will be in the additional drivers page.

sudo apt-get install bcmwl-kernel-source
sudo modprobe wl

That's sadly the only one I can remember trying (sorry, in and out of hospital, with lots of pain killers. Details are hard for me right now)
But all things yield no results.

Ubuntu 17.10 64-bit budgie environment.

Thank you in advance to anybody who can help me not need this 200 foot cable, just to have internet.

Alright, first little update on my problem...
Some further research on my own time, PCI ID 14e4:42a0 and BCM4360 are for my card, and reveal numerous amounts of information, most notably I've been looking through Installing Broadcom Wireless Drivers
Nothing has managed to get the card to be read by the system. Windows can read it fine however, so I know it is in fact functional.

Disabling secure boot in BIOS, followed by reinstalling everything. Suddenly it all began to work.

sudo apt-get purge bcwml-kernel-source

A quick reboot inbetween...

sudo apt-get install bcmwl-kernel-source

Once more, a reboot.

Each time I boot up, first thing I checked was the network status on the tray. This time, immediately on login, it already was displaying wireless options for me.
Checked through additional drivers, lspci, iwconfig, etc, etc. Everything is now showing the card as existing (and functioning)

Secure boot seems to have been preventing it from functioning.

Not knowledgeable enough on the subject to say anything else... Such as why. Maybe a comment will explain, sadly I cannot.

On my Clevo N240WU laptop I had the same symptom like you (Wi-Fi card not recognized in Linux and not shown in lspci output). I tried different kernels (4.10, 4.13; all the same).

This only happened when I used legacy BIOS. When using UEFI the Wi-Fi card worked.
