Patch https://lkml.org/lkml/2015/11/21/57 seems to fix it. I cannot
reproduce the issue after applying it (on top of 4.2.0-19 from GIT).

Title:
  Wireless is disabled by rfkill after suspend with linux-image-generic-
  lts-wily

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I am running Ubunutu 14.04 on Dell Latitude E5450; Ubuntu came
  preinstalled on this notebook. After installing kernel linux-
  image-4.2.0-18-generic wireless is not available after resuming from
  suspend to RAM; in logs I see

  Nov 20 13:04:46 bor-Latitude-E5450 NetworkManager[1389]: <info> WiFi
  now disabled by radio killswitch

  This problem did not exist with original kernel linux-image-3.13.0-xx
  from 14.04 and updates.

  Probably related - original kernel is using iwlwifi driver

  Package: iwlwifi-3.16.2-dkms
  Status: install ok installed
  Priority: optional
  Section: misc
  Installed-Size: 65,6 MB
  Maintainer: Ubuntu Developers <ubuntu-devel-discuss@xxxxxxxxxxxxxxxx>
  Version: 1.0
  Depends: dkms (>= 1.95)
  Original-Maintainer: Dynamic Kernel Modules Support Team <pkg-dkms-maint@xxxxxxxxxxxxxxxxxxxxxxx>

  This driver does not compile for kernel 4.2.
