> Andy Barry, to advise, it would be most helpful if simply one card is tested and advised to (not 3) so that this report may be precisely scoped, and dealt with.
The reason I wrote about the 3 different cards is that I think it indicates the bug is likely *not* in the wifi drivers for the cards, but in the driver for the motherboard / BIOS. For the purposes of this report, I'm happy to focus on the Intel 7265 which is the most well supported of the 3. > Hence, to clarify > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1555775/comments/18 : > 1) Which card did you test with specifically? > 2) Did you test http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-rc7-wily/ > or something else? I tested Intel 7265 with v4.5-rc7-wily, yes. Exactly that link with the amd64 packages. I'll change the status back to Confirmed since I've answered your questions, but please let me know if that's inappropriate and something you or someone else is supposed to do (I'm relatively new to bugs on launchpad). ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1555775 Title: WiFi + wired ethernet broken after suspend on Alienware 15 R2 Status in linux package in Ubuntu: Confirmed Bug description: 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: http://ubuntuforums.org/showthread.php?t=2311390&page=2 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. --- ApportVersion: 2.19.1-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: abarry 1585 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.10 InstallationDate: Installed on 2016-03-10 (0 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 1bcf:2b8c Sunplus Innovation Technology Inc.
