Title:
  WiFi + wired ethernet broken after suspend on Alienware 15 R2 (same on
  3x different WiFi cards)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have an Alienware 15 R2 where the WiFi is broken on resume from
  suspend.  I thought it was likely my WiFi card, but I have an
  identical issue regardless of the three cards I have tried:

  1) Killer 1535
  2) Intel 8260
  3) Intel 7265

  All three work before suspend (the Killer required a firmware
  download), but after suspend, they are gone from network manager ("No
  network devices available"), from ifconfig, and from lshw -class
  Network

  I have tried removing the kernel module for the driver (ath10k and
  iwlwifi, respectively) before suspend and modprobe-ing it after, but
  that results in no change.  I also have disabled wifi via  the
  keyboard key, then suspended,  then resumed, but still no luck.  No
  change after installing intel-microcode either.

  Wifi does come back after resume in Windows.

  This post reports a similar problem:

  So my conclusion is that there's something going on with the
  motherboard/BIOS not turning any of the ethernet devices back on.  I
  am running the most up to date BIOS version.  I have tried the
  following distributions with identical results:

  Ubuntu 15.10 (stock kernel and 4.3 kernel)
  Xubuntu 14.04
  Linux Mint 17.3

  dmesg of a suspend/resume cycle in Ubuntu 15.10 with the stock kernel
  running the Intel 7265: http://pastebin.com/UsvwSbbM

  version.log for that dmesg:
  Ubuntu 4.2.0-30.36-generic 4.2.8-ckt3

  lshw -class Network (before suspend): http://pastebin.com/yhpUKjwv

  lspci-vnvn.log: http://pastebin.com/W6zfHLxE

  As a final note, the exact same thing happens to my wired ethernet
  connection as well (it disappears from lshw -class Network) after
  suspend.
