Add broadcom wireless support in Ubuntu

When you install, or upgrade to, Ubuntu 11.04 you may notice that you can not use your Broadcom Wireless adapter. Many people have left Ubuntu and/or Linux for this reason. Yes, you can look online for a way to install the driver, but I’m going to show you how to quickly install the driver. The way I’m going to show you works in all Ubuntu derivatives.

First, open a Terminal, and enter:
sudo apt-get firmware-b43-installer

It will ask you for your password which you should enter. When the program has been successfully installed go back to your terminal and type in:
sudo apt-get install b43-fwcutter

Again, typing in your password.If you don’t wont to use the terminal you can open your package manager and search for bcm. Make sure you uninstall the bcmw1-
kernal-source package. Search for firmware-b43-installer and install
it, then search for b43-fwcutter and install that. Your wireless should
now work.. Remember, you need to have a wired network connection to do the
steps above!
