Thanks for the advice. It seems to make sense, but doesn't seem to get my wireless activated. This is what I did..
I refreshed the USB with a fresh copy of linuxmint-14.1-cinnamon-dvd-32bit.iso and then tried to install firmware-b43-lpphy-installer, but could not see it in synaptic. (Perhaps I mistyped something) So I installed b43-fwcuttter (that's all), and after that, I could see the firmware-b43-lpphy-installer in synaptic, so installed it. That's all I did. I then rebooted. The wireless card showed up in network settings, it tried to turn on, but then went off again and shows "unavailable". The following are in /etc/modprobe.d/
When I boot into Ubuntu, synaptic shows bcmwl-kernel-source as being installed and the wireless works. I also see that Ubuntu has a blacklist file containing these lines..
This guy (https://andym3.wordpress.com/projects/t ... ard-guide/
) seems to think we need to have bcmwl-kernel-source, but it compiles with errors under Mint (is this an issue or are these errors normal)..
ERROR: Module b43legacy does not exist in /proc/modules

Any further ideas?
