Pleased do:

sudo apt-get update
sudo apt-get install bcmwl-kernel-source

Reboot.

How to install the bcmwl-kernel-source package without an internet connection.

The bcmwl-kernel-source and dkms package and there required dependencies are on the livecd or liveusb disk that you installed ubuntu from.

Insert the livrcd or liveusb disk and navigate to pool > restricted > b > bcmwl and copy and paste the bcmwl deb package to your desktop.

Now do the same with pool > main > d > dkms.

Now install the deb files. Open the terminal with CTRL+ALT+_T and: 

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

  • At the moment i have no means of connecting my new laptop to the internet. I tried tethering my new laptop via my android phone (using Easy Tether) but could not get the Easy Tether program to sucessfully give my laptop a internet connection. Not sure how I can issue the above commands. I do not have access to net through ethernet at the moment. – Michael Dykes May 27 '14 at 17:12
  • Updated my answer with directions to install the driver without an internet connection. – Wild Man May 28 '14 at 01:25
  • Ok I was finally able to get some help from a friend of mine. He was able to get my new laptop tethered to his box and I was then able to run the commands suggested and Hey Presto: I now have wireless and wifi capabilites!!! Thanks Wild Man!!!! – Michael Dykes May 28 '14 at 14:54
