Public bug reported: 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Summary changed: - WiFi+ wired ethernet broken after suspend on Alienware 15 R2 (same on 3x different WiFi cards) + WiFi + wired ethernet broken after suspend on Alienware 15 R2 (same on 3x different WiFi cards) ** Description changed: I have an Alienware 15 R2 where the WiFi is broken on resume from suspend.
