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?

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.

I had the same issue on macMini

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

You will need to USB tether by phone or connect a network cable into your computer in order to install software over the internet.

Try using the software updates applette on the settings control center. Go to the drivers tab and select the proprietary device drivers for the Broadcom wireless.

That worked for me.
