Upgraded to Precise Pangolin, and everything broke again: the 5.60 driver does not seem to work anymore, and the 5.100 one doesn't work either (the driver fails with an "error 21", apparently).
After swearing and sweating for a couple of hours, I followed different advice, uninstalled bcmwl-kernel-source and installed b43-fwcutter + firmware-b43-installer (which didn't work in previous versions for me), and everything started working again.
