Hello. I am trying to use elementary on my macbook pro, but i won't display wifi unless i plug in usb wifi dongle. So, the drivers are missing i suppose. I had this issue before and it was solved with a system update. Now how can i fix and enjoy elementary os?
Following steps fixes the problem.
Removing bcmwl-kernel-source package, then reboot:
sudo apt-get remove --purge bcmwl-kernel-source sudo reboot
Installing new broadcom firmware:
sudo apt-get install firmware-b43-installer
sudo modprobe -r b43 sudo modprobe b43
