On Ubuntu 17.10, I have the Broadcom 43142A0 (0a5c:216c), and I have tried everything I have found on Broadcom that I can. I have no Internet on that machine. I download files on my Windows laptop and transfer files over.

I got the Bluetooth working using one of the solved solutions I found on here, but I can't seem to get the wireless working.

From what I've read, it seems I have a rarity among the Broadcom chipsets.

I'm new to Linux, so please explain like you were talking to a five year old.

The lspci -nn line for my network card:

01:00.0 network controller [0280]: broadcom limited bcm43142 802.11b/g/n [14e4:4365] (rev 01)

There's two driver setups for Broadcom Wifi, bcmwl-kernel-source and firmware-b43-installer. Some chips work with the former, some work with the latter. Don't have them both installed at the same time.

You need to install bcmwl-kernel-source for your chip according to this page. You can install it with Terminal command sudo apt install bcmwl-kernel-source. Some chips also work better if IPv6 is set to "Ignore" in Wireless properties.

You can download the .debs for 17.10 from here: https://packages.ubuntu.com/artful/bcmwl-kernel-source

Install it by running sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb. You may also have to download and install its dependencies.
