linux安装设置无线网卡

以下是我设置安装无线网卡的方法（我的网卡是TP-LINK wn823N)

其他网卡应该类是：

第一步：由于大部分的无线网卡的驱动是windows的（谁让人家大呢）所以第一步就遇到了驱动安装的问题，

           驱动问题一般解决可以先去查看网卡的芯片，看其芯片组的型号，去网上找到对应的芯片组的linux驱动（我的是rtl8192cu的芯片）

第二步：安装下载的芯片驱动，安装方法我就不说了（一般就是make执行，或者是./执行等）

第三步：如果安装成功，用lsmod查看网卡的驱动是否安装成功，安装成功之后，用iwconfig命令查看无线网络（一般是wlan0（我的是这个），或者是eth（这个我不知道...嘿嘿）什么的），安装失败我就不知道了啊...嘿嘿，我没遇到。

第四步：可以再用iwlist scanning命令查看周边的网络。

第五步：找到你想链接的网络

一般都是这样的，咱们需要看的就是ESSID""分号中的，还有channel后面的数字。其他的没啥可看的吧。

第六步：由于现在用的都是wpa的密码，我不知到这是什么东西啊，不过我我知道需要wpa_supplicant这个工具，需要安装这个，我用的时候很爽，因为我下载的驱动包里有..嘿嘿。

第七步：安装好wpa_supplicant这个工具之后，在命令行中输入wpa_supplicant这个命令会出现相关的提示。

第八步：该配置了，用iwconfig命令进行一些配置，我觉得似乎没用吧，我不知道有什么作用，以下是我的配置：

                iwconfig wlan0 txpower on

                iwconfig wlan0 essid """链接的路由命令

                iwconfig wlan0 key s: 密码

                ifconfig wlan0 on

第九步：这
4000
里我觉得很重要，运行

[zzh@localhost 桌面]$ wpa_passphrase ESSID

# reading passphrase from stdin

自己输入：密码，按回车一下是自动生成的，需要复制到etc/wpa_supplican/wpa_supplican.conf文件中。并保存

network={

    ssid="MERCURY_6BC91E"

    #psk="密码"

    psk=e92449164fa6bdc647cf10156292a2b28896033cc4931ef5025a68b6d7ef6e3e

}

然后连接就ok了。。
