Andy Barry, to keep this relevant to upstream, one will want to continue
to test the latest mainline kernel (now 4.18-rc3) as it is released.
Could you please advise?

Importance: Medium => Low
** Changed in: linux (Ubuntu)
Status: Triaged => Incomplete
** Description changed:
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.
