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.
