I finally got around to installing Ubuntu Desktop, Version 22.04, on my MacBook Pro 2014 since OS X stopped allowing upgrades on the device in 2021. While I replaced it in 2021 with a new MacBook Pro with an i9 Intel Chip. The Ubuntu documentation gave clear instructions on how to create a bootable USB drive before replacing the Mac OS software..

Unfortunately, networking was not well covered. It left me with two questions:

• How to configure Ubuntu Desktop 22.04 to the network?

  You need to use an RJ45 network cable (in this case also an RJ45 to Thunderbolt adapter) and reboot the OS. It will automatically configure your DCHP connection.

• How to configure Wifi for Ubuntu Desktop 22.04?

  You need to download and install a library, which is covered below.

After the Ubuntu Desktop installation, I noticed it didn’t provide any opportunity to update the software or configure the network. It also was not connected to the network. I connected the MacBook Pro to a physical Internet cable and rebooted the Ubuntu OS. It recognized the wired network. Then, I upgraded the installed libraries, which is almost always the best choice.

At this point, I noticed that the libraries to enable a WiFi connection were not installed. So, I installed the missing Wifi libraries with this command:

sudo apt-get install dbms bcmwl-kernel-source

After you’ve installed the bcmwl-kernel-source libraries, navigate to the top right where you’ll find a small network icon. Click on the network icon and you’ll see the following dialog. Click on your designated Wifi, enter the password and you’ll have a Wifi connection.

As always, I hope this note helps those trying to solve a real world problem.
