MacOS Wifi No Hardware Found Can't Get USB Wifi to Work Either

Getting external wifi dongle to work with MacOS requires third-party software...

I have a mid-2012 15" MacBook Pro (i7 quad-core 2.3 GHz, Nvidia 650M 512 MB / Intel HD 4000 1536 MB (I upgraded the 512 MB regular hard drive to a 2 TB SSD, 16 GB 1600 MHz DDR3 RAM some time ago)).

 In late 2019 the built-in wifi started switching off by itself after the last OS update/upgrade (now on macOS Catalina 10.15.4).

This only became worse and worse, until now my internal wifi no longer works. I disassembled the system to check all the connections on the wifi hardware and reassembled, and it came back up briefly, but yet again the OS switched it off after a while, and after a few weeks eventually stopped coming up at all.

I then tried using various external usb dongles I had handy that are Linux and OpenBSD (and Mac) compatible, but they weren't showing up at all even with /usr/sbin/network... -detectnewhardware command. 

Fortunately there is a free third-party app that helped address the external USB Wifi dongle issue though my builtin appears to be completely dead.

This is the main Github page:

Here is the download I used.

Unzipped, and ran package installer.

Mandatory reboot.

Then the USB dongles worked great!
