I am trying to use WiFi on my new laptop.

The laptop is "Acer Aspire R11 R3-131T-P7HR".

When I run

$ lspci | grep Network

I see this

02:00.0 Network controller: Intel Corporation Device 3165 (rev 81)

When I try to run this

sudo ifconfig wlan0 up

I only get

wlan0: ERROR while getting interface flags: No such device

I don't see wlan anywhere when running ifconfig. Some more outputs:

$ uname -a
Linux peepee 3.19.0-30-generic #34~14.04.1-Ubuntu SMP Fri Oct 2 22:09:39 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

$ rfkill list
1: acer-wireless: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

$ lspci -knn|grep Net -A2
02:00.0 Network controller [0280]: Intel Corporation Device [8086:3165] (rev 81)
    Subsystem: Intel Corporation Device [8086:4010]

The wi-fi worked when I used windows, before I removed it. What should I do/install?

Installing Ubuntu 15.10 fixed my issue.

I've got the same wifi card on my MSI GE62 6QD Apache Pro.

Installing the 15.10 beta did work for me, but then I had all of the problems associated with running a beta Ubuntu build.

But I managed to get it working on 14.04 with kernel 4.2.3. The newer kernel has support for the wifi card. However, this kernel seems to have some issues with older NVIDIA drivers. So, to get the graphics to work, I needed to install NVIDIA-352 from the edgers PPA.

Step by step instructions:

  1. Download and install Ubuntu 14.04.
  2. Make a temporary directory to store your downloads:
    • mkdir kern
    • cd kern
  3. Download the required kernel files:
    • wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.3-unstable/linux-headers-4.2.3-040203-generic_4.2.3-040203.201510030832_amd64.deb
    • wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.3-unstable/linux-image-4.2.3-040203-generic_4.2.3-040203.201510030832_amd64.deb
    • wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.3-unstable/linux-headers-4.2.3-040203_4.2.3-040203.201510030832_all.deb
  4. Install the kernel
    • sudo dpkg -i *.deb
  5. Remove old Nvidia drivers:
    • sudo apt-get purge nvidia*
  6. Install new Nvidia drivers:
    • sudo add-apt-repository ppa:xorg-edgers/ppa
    • sudo apt-get update
    • sudo apt-get install nvidia-352

Now when you restart, you should have an option in grub to boot Ubuntu with kernel 4.2. Do this and you should be good to go. If it doesn't work, blacklisting Nouveau might be necessary.

EDIT: On my MSI GE62, it's also critical that bumblebee and bumblebee-nvidia be installed.

sudo apt-get install bumblebee bumblebee-nvidia
