check synaptic package manager and see if b43-fwcutter is installed please
your ethernet I know is native ubuntu 11.04 and related distro's supported
I have gotten it to work via updated kernel and updated linux firmware in Ultimate Edition 2.9 but wasn't supported out of the box.
What system is this ?
I know your wireless is supported just fine. Might need to install bcmkernel source thou.
I always keep a USB wifi card on hand for times like these that is supported out of the box. So you can download and install the needed drivers.
