Ubuntu12.04下安装TL-WN322G+无线网卡驱动（RT5370芯片）

实验室有一块TL-WN322G+ USB无线网卡，于是就想着能不能在Ubuntu12.04下面安装驱动，捣鼓了两天终于成功了。

第一天

从晚上开始奋战，首先去TPLINK的官网找到了这块无线网卡的驱动，无奈TPLINK只给了windows的驱动，真的想吐槽一下国内的厂商出的设备对
linux的支持实在是，不过本人可没这么容易妥协，于是直接谷歌TL-WN332G+
LINUX，果然出来一堆资料，不过大部分的资料都是2008年之前的，参考了几个网页，主要的思路就是：TL-WN322G+无线网卡使用的是
ZD1211b的芯片组，所以我需要去下载ZD1211b芯片组的驱动程序，废了不少力气终于找到了ZD1211b的驱动程序（同样是08年更新的），然
后解压缩，make，刚敲下去就报错，各种头文件找不到，然后谷歌了一下，说是编译模块驱动需要内核源码，然后又去找内核源码，内核源码下好了以后设置好
头文件路径，还是各种头文件找不到，仔细一看，貌似这回是3.2内核源码里面也没有那些头文件，后来再google相关的词条，原来这块USB网卡的芯片
组只支持2.4以及2.6的内核，对于我ubuntu12.04的3.2内核，我只能说欲哭无泪。

第二天

早上到了实验室使用ndiswrapper安装还是不成功，本想着放弃吧，突然想起来实验室还有另一块USB无线网卡，找过来插上去之后居然能够直接识
别，而且Network
Manager里面居然已经能够直接配置无线网络，可是为什么第一快网卡就不行，想着想着本人就是不死心，于是继续google，鉴于昨天的经
验，google的时候我更加具体地搜索了USB设备号，设备号是从终端中使用lsusb获得的：

这回被我搜索到一个博客，博
主居然也和我遇到了相似的问题，看完一遍之后真的无力吐槽了，原来这块网卡的USB ID
f201:5370对应是新版的芯片组，使用的是RanLink的RT5370芯片（即TL-WN322G+
V3）。现在问题很清楚了，我只要去找RanLink的RT5370的Linux驱动就OK了，现在看来TPLINK这类公司也都是买国外的芯片回来包装
一下，离自己生产IC差远了。不过之前那位博主的博客我只能参考一半，由于他用的是3.4的内核，而我的3.2内核对于RanLink无线网卡的驱动支持
还没到位，所以我决定自己编译模块驱动，这样对于驱动安装流程也有一个大体的了解，找到RanLink官网的驱动链接：http://www.mediatek.com/_en/07_downloads/01_windows.php?sn=501

果然这方面还是国外的厂商比较给力，不仅有windows，还有Linux和Mac的驱动。下载驱动之后还有几个地方需要修改：

将2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO.bz2解压以后

1. 修改源码包下的 os/linux/config.mk 文件（将原来的n改为y）：

# Support Wpa_Supplicant

HAS_WPA_SUPPLICANT=y

# Support Native WpaSupplicant for Network Maganger

HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

2. 修改usb口识别的文件 rtusb_dev_id.c文件这个文件在源码包的common/rtusb_dev_id.c，如果没有你的设备的usb id号的话就要在里面添加lsusb命令后得到的id号，红色粗体字是需要添加上去的：

#ifdef RT5370

{USB_DEVICE(0x148F,0x5370)}, /* Ralink 5370 */

{USB_DEVICE(0x148F,0x5372)}, /* Ralink 5370 */

{USB_DEVICE(0x13D3,0x3365)}, /* Azurewave */

{USB_DEVICE(0x13D3,0x3329)}, /* Azurewave */

{USB_DEVICE(0x2001,0x3C15)}, /* Alpha */

{USB_DEVICE(0x2001,0x3C19)}, /* Alpha */

{USB_DEVICE(0x2001,0x3C1C)}, /* DLink */

{USB_DEVICE(0x2001,0x3C1D)}, /* DLink */

{USB_DEVICE(0x043E,0x7A12)}, /* Arcadyan */

{USB_DEVICE(0x043E,0x7A22)}, /* LG innotek */

{USB_DEVICE(0xF201,0x5370)}, /* TP-LINK TL-WN322G+ v3 */

#endif // RT5370 //

注意：这一步很关键，网上好多教程都没有解决问题，就是因为这一步，这就是USB无线网卡识别的关键部分

接下来进行编译和安装

不过在编译之前需要当前Ubuntu发行版的Linux内核源码以及编译工具，安装如下开发包即可：
 
 sudo apt-get install build-essential linux-source
 
接下来即可开始编译：

        <div>
            <span class="pln">sudo make</span>
        </div>

        <div>
            <span class="pln">sudo make install</span>
        </div>

4. 接下来加载驱动模块

    <p>
        <span class="pln">sudo modprobe rt5370sta</span>
    </p>

5. 一般到第4步就能用了，不过我到了第4部还没有成功，于是接下来将驱动模块添加到开机启动列表，注意这一步需要在root用户下操作

            <div>
                <span class="pln">sudo </span><span class="pun">-</span><span class="pln">i</span>
            </div>

            <div>
                <span class="pln">echo rt5370sta </span><span class="pun"></span><span class="pln"> </span><span class="str">/etc/</span><span class="pln">modules</span>
            </div>

重启系统后在面板上就能看到无线网卡识别出来了，并且能够通过Network Manager配置无线网络
