Which Broadcom STA driver do I install from the ones listed in Synaptic?

[klaus2008]

I think step #5 has finished and you were trying to install the new package using

sudo m-a install broadcom-sta-source

Did you also try the instructions I gave at step #6?

I think that you could also try

sudo apt-get install broadcom-sta-common
sudo m-a install broadcom-sta-source
