Andy Barry, could you please provide the missing information from
https://wiki.ubuntu.com/DebuggingKernelSuspend ?
** 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:
+ 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.
- 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.
+ I have tried removing the kernel module iwlwifi,before suspend and

Wifi does come back after resume in Windows.
- This post reports a similar problem:
- http://ubuntuforums.org/showthread.php?t=2311390&page=2
+ 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.
- 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.
