apport information
** Tags added: apport-collected wily
** Description changed:
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.
