I am dual booting OS X 10.8 and Ubuntu 13.10. I can't seem to get the situation right to have wifi. I have tried so many different tutorials and follow alongs on you tube and nothing seems to work. I don't have a cat5 so can't create a wired connection. I've been moving things from computer to USB drive to computer. I've got a Broadcom 4321. I believe I've installed the driver and the firmware and rebooted but still get nothing. I'm really new to terminal so I don't really know what the scripts mean. Help!
