install intel wireless 3165 driver for ubuntu 14.04.1

Ubuntu 14.04.1 with 3.13 kernel can’t drive the new Intel Wireless 3165 AC with firmware version 13.
This is about how to install the driver mannually.

Today I changed a new Dell vastro 5000 series laptop with the Intel 3165 Wireless AC.
After os installed, I find I can’t find the wireless network.

As iwlwifi official site shows, Intel® Wireless 3165 (starting from firmware XX.XX.13.0 and kernel 4.1).
Thanks God we have backports, which provide drivers released on newer kernels backported for usage on older kernels.

Mannul Install

1. Download & compile the driver. Maybe the latest stable version is better. But I didn’t use it.

1 sudo apt-get update2 sudo apt-get install linux-headers-generic build-essential3 wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz4 tar -zxvf backports-20151120.tar.gz5 cd backports-201511206 make defconfig-iwlwifi7 make8 sudo make install

1. Verify that you have the latest firmware:
   • iwlwifi-7265D-13.ucode
   • iwlwifi-7265-13.ucode:

1 ls /lib/firmware | grep 7265

1. Make copies:

1 cd /lib/firmware2 sudo cp iwlwifi-7265D-13.ucode  iwlwifi-3165-9.ucode3 sudo cp iwlwifi-7265-13.ucode  iwlwifi-3165-13.ucode

1. Reboot. Your wireless should be working.

Hints

You will need to recompile every time installs a new kernel:

1 cd backports-201511202 make clean3 make defconfig-iwlwifi4 make5 sudo make install
