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?
