You need to install firmware-b43-installer.

If you do not have an alternative internet connection, do it this way.

If you installed bcmwl-kernel-source, then remove it.

sudo apt-get purge bcmwl-kernel-source

Download these files http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_015-9_amd64.deb http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2

Copy them to your Ubuntu Home folder.

Run in terminal

sudo dpkg -i b43-fwcutter_015-9_amd64.deb
tar xfvj broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

Reboot or run:

sudo modprobe b43
