How do I install BCM4312 wireless drivers?

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

This question was marked as an exact duplicate of an existing question.

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

Done firmware-b43-installer is already the newest version. The following package was automatically installed and is no longer required: libzlcore Use 'apt-get autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. baskint@leibniz:~$ – baskint May 8 '11 at 12:53
