【转】install intel wireless 3165 driver for ubuntu 14.04.3

Ubuntu 14.04.3 with 3.19 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 update
2 sudo apt-get install linux-headers-generic build-essential
3 wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
4 tar -zxvf backports-20151120.tar.gz
5 cd backports-20151120
6 make defconfig-iwlwifi
7 make
8 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/firmware
2 sudo cp iwlwifi-7265D-13.ucode  iwlwifi-3165-9.ucode
3 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-20151120
2 make clean
3 make defconfig-iwlwifi
4 make
5 sudo make install
