How do I install BCM4312 wireless drivers?

Below are the results for sudo lshw -c network command. I believe "UNCLAIMED" refers to missing drivers.

The STA driver in 11.04 doesn't work due to a kernel issue. You will have to install the B43xx firmware. Just install firmware-b43-installer from the software center or synaptic.

You can also do it from the command line.

sudo apt-get install firmware-b43-installer
