Debian 7.6 Wheezy 安装 Intel® Wireless 7260 wifi 模块驱动和固件的方法。

0. 内核以及发行版 Version 信息
    Debian 7.6 Wheezy
    Linux fyp-tp 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux


1. 获得 PCI device numbric ID
    $ lspci -nn # 可以显示设备号和subsystem ID
    ....
   04:00.0 Network controller [0280]: Intel Corporation Device [8086:08b2](rev 6b)
   在下面的网站可以根据设备号(0x808) 和 subsystem ID(0x08b2) 查找到设备型号:
   http://pci-ids.ucw.cz/read/PC
   可知 wifi 模块的型号是: Intel Wireless 7260

2. google 可知这个 wifi 模块使用 iwlwifi wireless driver。
    这个驱动包在 Debain nofree 源中。 使用 Debian nofree 源:
    $ sudo echo '# Debian 7 "Wheezy"' >> /etc/apt/sources.list
    $ sudo echo "deb http://http.debian.net/debian/ wheezy main contribnon-free" >> /etc/apt/sources.list

   安装完驱动后,要安装相应的固件,可以在
   http://wireless.kernel.org/en/users/Drivers/iwlwifi
   找到相应的固件包, 解压后使用 root 用户安装:
   $ cp iwlwifi-*.ucode /lib/firmware

3. 但是,Debian提供的 iwlwifi 驱动模块是 3.2.60 Linux Kernel 版本的,
    并不支持 Intel Wireless 7260 这个 wifi 模块.
    iwlwifi 驱动支持 7260 wifi 模块要求: 最低 Linux Kernel 版本 3.10+.
    但是,在 Debian 升级 Linux Kernel 不是一个好的解决方案。
    好消息是:可以使用 linux kernel backports 来编译本应该运行在高版本内核的驱动, 
   编译的得到驱动可以在低版本的内核上运行, 并且支持 wifi 模块。
   "If you need to use the current driver on an older kernel, you can use
   the compat-drivers project for that. See https://backports.wiki.kernel.org/
   for more information."


4. 下载 backports-3.14-1 在 http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/
    需要打一个 patch: http://www.mail-archive.com/backports@vger.kernel.org/msg01790.html
    配置以及安装,参考: https://backports.wiki.kernel.org/index.php/Documentation

   #可以只配置 wifi 模块的驱动:
   $ make defconfig-wifi

   #可以选择只编译 iwlwifi
   $ make menuconfig 
       [*] Wireless LAN ---> 
               Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi) 

   $ make
   $ sudo make install
   $ sudo update-initramfs

5. 在 http://wireless.kernel.org/en/users/Drivers/iwlwifi 下载:
     iwlwifi-7260-ucode-22.1.7.0.tgz
     iwlwifi-7260-ucode-22.24.8.0.tgz
     iwlwifi-7260-ucode-23.214.9.0.tgz
    三个固件包并且安装到 /lib/firmware 
    如果没有安装固件的话, dmesg 信息中会有 iwlwifi-7260-7.ucode 找不到之类的信息.
    没有测试是否也需要 iwlwifi-7260-9.ucode. (我在安装 iwlwifi 驱动之前就安装了这个固件)

Your system might already have an inbox Wi-Fi driver installed by Windows*. There is no "Delete the driver programme for this device" option available for these kinds of drivers. If, after conducting the uninstall procedure, arthritis & rheumatology you observe the same version of the driver being installed automatically, move on to the following step.

To install the Intel® Wireless 7260 wifi module driver and firmware on Debian 7.6 Wheezy, you need to first download the driver from the Intel website. Once you have ac joint pain downloaded the driver, you need to unzip it and then run the "install.sh" file. After the installation is complete, you need to reboot your computer for the changes to take effect.
