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. --- 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.
