I'm new on Ubuntu system and i do not manage to run the Wifi, I am using Ubuntu with a dual boot on a Macbook Air 6,2,
Type of card : AirPort Extreme (0x14E4, 0x117)
Version of internal program : Broadcom BCM43xx 1.0 (18.104.22.168.63)
The easiest way to do this would be to connect to Ethernet (via usb dongle) and run
If you are not able to get access to Ethernet, you can download this file on another machine, transfer it via usb, and install it that way.
