I did a fresh install of 14.04 and now my wireless is not working. I don't see it in the status bar. Using unity desktop. 

03:00.0 network controller [0280]: broadcom Bcm43228 802.11a/b/g/n [14e4:4359]]
0c:00.0 Ethernt controller [0200] : realtek semiconductor Co., Ltd. RTL8111/8168/8411 pci express gigabit Ethernet controller [10ec:8168] (Received 07)

I don't have an wired connection for the laptop. Writing from phone.

Best Answer

Your Broadcom 14e4:4359 uses bcmwl-kernel-source. It and its dependency dkms are on the installation DVD or USB. Insert the install media and navigate to pool > restricted > b > bcmwl and drag and drop the bcmwl deb package to your desktop. Do the same with pool > main > d > dkms. Now we install the deb files. Open a terminal and:

cd ~/Desktop
sudo dpkg -i *.deb
sudo modprobe wl

Your wireless should now be working.
