I have already install a clean Ubuntu 12.04 in an Acer. After the installation, the wifi was not detected. I have followed several bcm431X tutorials (from this forum), but no-one worked out.
In summary, I have tried installing b43-fwcutter & firmware-b43-installer packages, and also, in first instance, bcmwl-kernel-source.
Here is the lspci output.

What can I do to solve the problem?
Thanks in advice.
