Alienware 17 R4 Ubuntu 16.04 WiFi driver

I have installed Ubuntu 16.04 on my new Alienware 17 R4 laptop that comes with Killer 1550 WiFi network card. Currently I am running on LAN cable to connect to the internet but would very much like to make use of my WiFi card. I have tested that it works well in Windows 10.

How do I get Killer 1550 installed on Alienware 17 R4?

The following are my outputs from sudo lshw -C network:

hello@world:~$ sudo lshw -C network

I can certainly use my ethernet hence I believe I do have the Qualcomm Atheros driver. Probing further on my network controller (WiFi card?):

hello@world:~$ lspci -knn | grep Net -A2

In case this could be of any useful information, my current linux kernel is:

hello@world:~$ uname -r
4.13.0-37-generic

Thank you all for reading and your kind assistance in getting my wifi to work!

P.S.: I tried suggestions found here Wifi not working in Ubuntu 16.04 LTS on an Alienware 17 R4 but it doesn't work for me.

Solution 1:

Intel recently added the VID and PID to their backports, to install

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

After a kernel update you will need to

cd backport-iwlwifi
make clean
make defconfig-iwlwifi-public
make -j4
sudo make install
