I tried kernel 4.18-rc4 after I saw your post, Christopher, and this bug is fixed. Wifi, ethernet, and nvme drive all work after suspend/resume now. I haven't tried any kernels between this and 4.13.0, so I can't say which version fixed it.
Kernel 4.18-rc4 Kubuntu 18.04 with the latest package updates Alienware 15 R2 BIOS 1.4.4 01/08/2018 Thanks for fixing it! This makes a big difference in my productivity and decision to not buy a new laptop. -- 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: [Dell Alienware 15 R2] WiFi + wired ethernet broken after suspend Status in linux package in Ubuntu: Invalid Bug description: 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. 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.
