Linux中Wi-Fi无线网络和AP无线热点的配置教程
0.Linux下的Wi-Fi配置无线网络飞速发展的今天,许多设备都提供了连接无线网络的源码功能。
那么Linux下的源码wifi到底该怎么配置、连接呢
开始配置之前,源码我们要说说iw家族。源码购票网站系统源码iw是源码stl源码口诀linux下常用的wifi配置工具,网上有相应的源码库和源码。全名为wirelessTools。源码
配置wifi模块,源码并连接相应的源码无线网络过程:主要使用iwpriv命令
(1)扫描可用的无线网络:
代码如下:
iwlist wifi-name scanning其中wifi-name为无线网卡的名字,比如网卡eth0就是源码系统默认的网卡名字, wifi-name可以用ifconfig查看,源码一般为ra0。源码网站源码python
(2)看扫描到的源码网络信息,按要连接的源码网络类型进行配置。以下为扫描到的网络:
代码如下:
iwlist ra0 scanning===rt_ioctl_giwscan. () BSS returned, data-length =
ra0 Scan completed :

如上:ESSID项的值即为无线网络的名字,如上的插件源码推荐jxj_rd等。如果值为空,说明在无线路由勾选了隐藏ESSID的选项。
ESSID是很关键的,如果被隐藏了,dnspy编译源码也不是不能连接,而是需要破解,用到其他的工具,非常麻烦。至于如何破解,不是本文叙述的内容,有兴趣的朋友可以网上搜索。
得到了网络的信息,接下来就是配置连接选项了。以连接jxj_rd为例,我们看看具体的过程:
(1) 设置要连接的网络类型:
代码如下:
iwpriv ra0 set NetworkType=Infra(2) 设置要连接的无线网络的安全模式:
代码如下:
iwpriv ra0 set AuthMode=WPA2PSK(3) 设置网络加密方式:(CCMP即为AES)
代码如下:
iwpriv ra0 set EncrypType=TKIP(4) 设置连接时的密码:
