本文是在正确安装好wifi驱动后对系统进行的配置。

1. 配置wpa_supplicant的配置文件

在加载驱动之前在/etc下新建目录/wpa_supplicant/wpa_supplicant.conf

配置好需要的wifi的ssid及psk即可

具体配置如下 ：

#vi wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

update_config=1

eapol_version=1

fast_reauth=1

network={

ssid="wifi名称"

psk="密码"

priority=1

}

2．加载驱动： insmod /lib/modules/3.4.39/8723au.ko

3．启动wifi:

# ifconfig 获取wifi名称 一般是wlan0

# ifconfig wlan0 up

4．后台运行wpa_supplicant:

wpa_supplicant-d -Dnl80211 -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf &

其中 ：

wpa_supplicant：可执行程序

–d ：增加打印信息

-Dnl80211： 驱动名称

-iwlan0：wlan0，网络接口名称

/etc/wpa_supplicant/wpa_supplicant.conf：wpa_supplicant的配置文件path

5. 为wlan0动态分配ip地址：udhcpc -iwlan0

打印如下： udhcpc (v1.18.3)started

Sending discover...

Sending select for 192.168.1.110...

Lease of 192.168.1.110 obtained, lease time 7200

deleting routers

route: SIOCDELRT: No such process

adding dns 192.168.14.12

adding dns 192.168.1.1

6. 查看wlan0状态：# ifconfig

打印如下：

wlan0 Link encap:Ethernet HWaddr CC:D2:9B:6E:6C:00

inet addr:192.168.1.110 Bcast:255.255.255.255 Mask:255.255.255.0 inet6 addr: fe80::ced2:9bff:fe6e:6c00/64Scope:Link

7. ping 网络测试
