No wireless device found. Wired internet only.
$ sudo modprobe wl
FATAL: Module wl not found in directory /lib/modules/4.8.0-37-generic
What?
Also, at the same time, I can no longer boot into Windows, perhaps this Ubuntu update also wrecked my Windows partition? What next?
Overnight, ethernet lost the ability to actually load web pages. It will still say connected to the internet in the icon, but cant load any web pages. Can ping 8.8.8.8. This is exasperating. Fixed this emergent problem by re-doing resolv.conf a la DNS_PROBE_FINISHED_BAD_CONFIG error in Ubuntu 14.04. Very strange that this emerged overnight, while the system sat idle unconnected to anything but its charger.

This is insane, but, by fixing the Windows and making it bootable, and doing literally NOTHING to the Ubuntu partitions whatsoever, now the wireless works as if nothing ever went wrong. Just finds saved network at login like it always did. I have no idea how the hell Windows reached out of its partition and into Ubuntu's to make this problem happen. I'm deeply bothered by this idea, but no idea what else it could be. Obviously, nothing changes in Ubuntu while I'm in Windows Command Prompt recovering Windows, trying to Reset Windows (that failed), and then suddenly Ubuntu is magically fixed?
