Broadcom b43 WiFi driver for Ubuntu on Macbook

 I like Linux, and this time I installed on old Macbook Pro 2010, however the wifi is not working after Ubuntu installation. Read more how to get working wifi on Ubuntu 20.10

First download these two files

http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_015-9_amd64.deb

http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2

and save to Desktop

Open Terminal in Ubuntu and write these commands below, after each line press enter in terminal. After first SUDO command write your login password and press enter!

cd Desktop

sudo dpkg -i b43-fwcutter_015-9_amd64.deb

tar xfvj broadcom-wl-5.100.138.tar.bz2

sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

sudo modprobe b43

Then reboot

It should work, if not you have different wifi card or some thing else!
