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

The first line only is what I have to do on my dv5000 series, except I don't mess with the firmware-b43legacy-installer. You might have to use it though. I don't even have to reboot, I just make sure the manual switch is turned on for the wireless. If you don't want to do it through console you can use Synaptic Package Manager and search for it there. I still have to use it on 12.04. –  lqlarry Apr 11 '12 at 5:32

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
