And reboot, and you are good to go.

WIFI Killer 1550 fix ubuntu 16.04 Alienware 15 R4

The card gets reported as: Intel Corporation Device 2526 (rev 29) on lspci -v.

On lspci -nnk | grep -i net -A2:

45:00.0 Network controller [0280]: Intel Corporation Device [8086:2526] (rev 29)
	Subsystem: Bigfoot Networks, Inc. Device [1a56:1550]

And sudo lshw -C network:

  *-network UNCLAIMED
       description: Network controller
       product: Intel Corporation
       vendor: Intel Corporation
       physical id: 0
       bus info: pci@0000:45:00.0
       version: 29
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress msix cap_list
       configuration: latency=0
       resources: memory:9db00000-9db03fff

To get the driver (from askubuntu):

sudo apt-get install git
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install

And reboot. On any kernel update you'll need to do sudo make installwe-16.04 again (until this is fixed upstream).

@xumingjie1658 yeah, we have a few of Alienware 15R4 in my lab.

You can ignore the nvidia stuff. That's old, for Ubuntu 14.04. But how to deal with the harddisk and Windows 10 may be helpful.

For nvidia in those I did:

From the nvidia CUDA download site for Linux > x86_64 > Ubuntu > 16.04 > deb(network):

cd ~/Downloads
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_10.0.130-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1604_10.0.130-1_amd64.deb
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
sudo apt-get update
sudo apt-get install -y cuda
