How to Install Broadcom / STA Wireless card (BCM43XX)

I have installed Ubuntu 10.04 on my HP dv6-1245 dx notebook and I do not have any wifi (it worked perfectly in windows vista and 7). I have followed a lot of instructions found on net but still not able to get Internet. Here is the outcome of lspci:

Open a terminal and install the following:

sudo apt-get install b43-fwcutter firmware-b43-installer firmware-b43legacy-installer

If "An unsupported BCM4312 Low-Power (LP-PHY) device was found." also install

sudo apt-get install firmware-b43-lpphy-installer

Then reboot

Try this driver.
sudo apt-get install firmware-b43-installer
and if that fails, remove it and try
sudo apt-get install bcmwl-kernel-source
