Removing the kernel modules for the card reader:

sudo rmmod rtsx_pci_sdmmc
sudo rmmod rtsx_pci_ms
sudo rmmod rtsx_pci

It still appears in lspci (but as unassigned)
After a suspend cycle, it is gone just like before, along with the wired and wireless ethernet.


Removing the kernel module for the wired ethernet:

sudo rmmod alx

Same as above: wired ethernet still appears in lspci.  After a suspend
cycle, it is gone along with the other two items, just as before.

Title:
  WiFi + wired ethernet broken after suspend on Alienware 15 R2

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  With Ubuntu 14.04, and 15.10, using my Alienware 15 R2 the Intel 7265
  WiFi is broken on resume from suspend. However, after suspend, it is
  gone from network manager ("No network devices available"), from
  ifconfig, and from lshw -class Network. It works fine prior to
  suspend.

  I have tried removing the kernel module iwlwifi,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.

  As additional data points:
  This also happens with WiFi cards Killer 1535, and Intel 8260.
  Also, the exact same thing happens to my wired ethernet connection as well (it disappears from lshw -class Network) after suspend.
