  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.
