No Wireless When Install 14.04 on Macbook Pro
So I'm attempting to dual-boot OS X 10.8.5 (native OS) and Ubuntu 14.04. I installed Ubuntu (hooray!) but upon booting into Ubuntu I discovered I have no network connection from the OS. I'm very new to Linux.
I've noticed some similar posts, however the only "solution" I've seen so far is to screw the wireless connection and buy a USB-ethernet adapter. If I was using this computer at home that'd be fine. But this is in an office and it's WiFi only.
Is there anyway to get the wireless adapter to work?
Mac Book Pro, Retina, 13-inch, Late 2012 CPU 2.5 Ghz Intel Core i5 Memory 8GB

Solution 1:
Please do:
sudo apt-get update
sudo apt-get install firmware-b43-installer
Reboot if it does not connect post a new file from the script.
No internet:
Download the b43updated.zip file to a usb flash drive then drag and drop the file to your ubuntu desktop. Right-click it and select Extract Here.
Open a terminal and do:
sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/* /lib/firmware/b43
sudo modprobe -rv b43
sudo modprobe -v b43
if it does not come on reboot.
Solution 2:
I had the same issue on macMini
>lspci -nn
02:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)
and this worked for me:
sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source
sudo apt-get install linux-firmware-nonfree b43-fwcutter firmware-b43-installer
and then a reboot
