Public bug reported: On upgrading a Dell M4400 from Trusty 14.04.3 to Xenial 16.04.1, the Broadcom wireless (which had been working in Trusty) failed to load. It's a Broadcom 14e4:432b according to lspci.
On installing Xenial in another partition, the Broadcom wireless worked flawlessly. I would rather not revise all of my settings to this partition, as there is a _very_ large number of them.
