Installing Broadcom BCM4322 Driver for Linux Mint 20 (Ulyana) in Macbook Pro 2009

I got an old MacBook Pro 2009 from a friend, and the hardisk is busted. After getting a brand new Apacer Panther SSD, I managed to replace the disk, and I tried to revive the old machine using MacOS internet recovery process.

Unfortunately, this model does not have the internet recovery feature. To make a usb recovery for macos, it is highly advisable to do it from a mac, and I do not have any spare mac.

So I decided to boot a linux mint 20 live usb, and it is surprisingly working well, except the wireless driver is not installed by default.

In order to install the driver, I need to know the model first. This can simply be achieved using "lspci" command

$ lspci | grep i wireless

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)
 

Now that we know the wireless card model and maker, I connect a network cable to the machine, and start researching for the solution. I found the solution here.

And below is how to do it.

You need to install a package called bcmwl-kernel-source from the repository.

$ sudo apt update

$ sudo apt install bcmwl-kernel-source -y

 

Once installed, you can now connect to your wireless, and that is all, folks.
