I got this bug after upgrading wpasupplicant from version 2:2.4-1.1 to version 2:2.6-11. None of my attempts to bring wifi back wasn't successful, until I rolled back wpasupplicant to 2.4. I use Broadcom Limited BCM4352 802.11ac Wireless Network Adapter (rev 03) (14e4:43b1) with broadcom-sta-dkms driver (wl.ko).
