Fix "No Wifi Adapter" in Ubuntu 20.04

Was having a great day, everything was working as well as it could be. Suddenly. BANG! "No Wifi Adapter Found" on my Macbook running Ubuntu 20.04. After lots of googling, and trial & error. It worked. I'm writing this in hopes that it will help someone who was in my predicament.

Step 1 : Find an internet connection. I tethered my phone to macbook with a USB cord.

Step 2: Open your terminal and run the following :

sudo apt-get purge bcmwl-kernel-source
Enter fullscreen mode Exit fullscreen mode
sudo apt-get install broadcom-sta-source broadcom-sta-dkms broadcom-sta-common
Enter fullscreen mode Exit fullscreen mode

Then Reboot. Should work. It did for me. Good luck.

Just curious, why Ubuntu on a Mac? (I run Ubuntu on Desktop and Laptop, but mostly because I cant stand Windows)

machine suckier. It got to the point where id have to buy a new one. I wasn't interested in spending the money and I got away from the iOS ecosystem so it felt right as I became more into linux over the last couple of years

because after the last update old macs become very slow. I have macbook pro 13 inch late 2013 (i5 8gb ram 256 ssd). With ubuntu my machine works great now which is expected.
