I'm also seeing the same problem on a Dell XPS 13 9343 - Wifi is
suddenly non-functional, whereas it'd otherwise been working fine for
many years (I'm unsure exactly when the problem started, as I mostly use
my laptop via wired ethernet, but it's definitely broken within the last
couple of weeks).
I've tried booting the previous kernel 3.19.0-80-generic from the grub
boot menu, but that also results in non-functional wifi. I've included
(hopefully) relevant info below, but please let me know if there's
anything else I can do to help.
