With a computer with working internet go to http://packages.ubuntu.com/utopic/amd64/bcmwl-kernel-source/download and select a mirror site to dowload from. Copy the file to a USB, DVD or whatever to get in on the Ubuntu pc and double click on it to install

My laptop has the same wireless hardware. The easy solution is: When you install ubuntu, check the box which says install third party software(wireless driver included in that). Then everything works out of box.

Do the command:

sudo gedit /etc/NetworkManager/NetworkManager.conf

This will open up that file in a text editor. Change the line that has managed= to:

managed=true

Save and close the file, then do:

sudo killall NetworkManager

Logout and log back in again. Answer taken from: Ubuntu 12.10 - network manager not listing wireless networks
