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.

Title:
modprobe: ERROR: could not insert 'wl': Package not installed
ubuntu14.04.5LTS kernel 3.13.0-165-generic
Status in bcmwl package in Ubuntu:
Confirmed
Bug description:
when installing bcmwl-kernel-source to build wl.ko
package version: 6.30.223.248+bdcom-0ubuntu0.2
Expected behavior: kernel module wl.ko loads.
What happened: finit_module returns ENOPKG
My device is: BCM4352 [14e4:43b1] (rev 03)
Happened after latest OS update, downgrading kernel to 164 did not
fix, downgrading package did not work.
secure boot mode is off.
A few others are having this issue
https://ubuntuforums.org/showthread.php?t=2413303
There is a possibility it is a modaliases problem -- 2015 chagelog
states that there was a capitalization problem, but I don't know how
to check this.
