Install 14 cinnamon to my old laptop, it requires ndidwrapper to get my bcmwl5 wirless card to work. No luck, but discovered that ndiswrapper.ko was not loading. I think this is the code to let one modprobe ndiswrapper.
One solution in ubuntu suggested that I did not need ndiswrapper. Instead in a terminal i typed:
sudo apt-get install bcm-sta-source bcm-sta-common
It worked for me. Now have a pretty, efficient and fully functional laptop. Thanks Mint folk!
Hope this helps somebody else
