Need driver for a Broadcom BCM943142HM for Ubuntu

My interpretation of the information on https://wikidevi.com/wiki/Broadcom_BCM943142HM is that the standard Broadcom wl driver (version 6.30.223.126 or higher) should work.

I recommend that you try installing the package bcmwl-kernel-source

went to that link and got a page talking about it . . Where is the file at ?

Just install the package bcmwl-kernel-source which is provided in the Ubuntu software repositories, e.g. with the command

sudo apt- install bcmwl-kernel-source

I need the file to put on the tiny thing ( HP 13-c200dx ) as it is not on line ( at Library with my laptop and the tiny thing to get file for it and transfer to it via flash drive . . And how do I install the file to the tiny HP thing

My Laptop is on line not the HP 13c2oodx LAPTOP AS it does not have any way
of going on line so i need the file to add or install it . . I REMEMBER
from a few hundred years ago something about this B43 cutter file . .Even
had Instruction in a file for it GEEZ long ago like maybe Ubuntu 10 . . or
12 . .

The easiest way would be to connect your laptop to a wired network and to install the bcmwl-kernel-source package with a single command.
Some USB WLAN stick work output of the box. Another possibility would be to temporarily borrow one and plug it into your system. If it works, you could then use that connection to install the driver for your built-in device.

If you cannot connect to a network, you have to install the required driver packages manually.
To be able to tell you the files to download and to install, we need some further information about your system.

What is the last part of the output of the command
uname -a
What release name do you get for the command
lsb_release -crid
Do you see a version number shown besides "installed" for the command
apt-cache policy dkms

oops, wrong autocorrect, should have been … work out of the box …

What is the last part of the output of the command
uname -a

Linux Notebook-PC-13 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

What release name do you get for the command
lsb_release -crid

Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic

Do you see a version number shown besides "installed" for the command
apt-cache policy dkms

N: Unable to locate package dkms

Do you see any possibility to temporarily connect that new laptop to the internet?

If not, then this is ging to be laborious.
As far as I can see, you would need to download the following packages:

Put them into a directory without any thing else and install them with the command (from within that directory):

sudo dpkg -i *.deb

Sorry, it seems that some of the file names are not correct, I will have to do some more tests.

Ok, corrected.

I hope that helps.

Thanks I . . It worked and can see the WiFi Connections . .Just can't get past Star Bucks sign on so will go to Library and get it up dated there . .Saved me buying a USB WiFi unit to plug in and get it running . . Might get it any way for next time I get a Weird Laptop to get running again . .
