Debian 9 “Stretch” 安装 Intel 7260 无线网卡

按照官方描述，进行安装，完全无法安装，最后还是在国外一家网站，找到sh脚本，进行安装成功，现分享给大家：

以下是官方描述：

Debian 9 "Stretch"
Add a "non-free" component to /etc/apt/sources.list, for example:

# Debian 9 "Stretch"
deb http://httpredir.debian.org/debian/ stretch main contrib non-free
Update the list of available packages and install the firmware-iwlwifi package:

# apt-get update && apt-get install firmware-iwlwifi
As the iwlwifi module is automatically loaded for supported devices, reinsert this module to access installed firmware:

# modprobe -r iwlwifi ; modprobe iwlwifi
Configure your wireless interface as appropriate.

以下是安装脚本

#!/bin/bash
