YuzuKi X 100ask V851s 连接wifi

1 ifconfig

验证是否存在 wlan0 接口（如果该命令正常执行说明驱动程序已启动并且 WiFi 固件已加载）：

1.1 检查 WLAN 接口

root@TinaLinux:/# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

wlan0     Link encap:Ethernet  HWaddr B8:15:AB:F9:9E:2A
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

1.2 初始化WLAN接口

打开wlan0

输入ifconfig就能看到有wlan0了

root@TinaLinux:/# ifconfig wlan0 up
[  426.715971] ieee80211_do_open: vif_type=2, p2p=0, ch=3, addr=b8:15:ab:f9:9e:2a
[  426.724274] [STA] !!!xradio_vif_setup: id=0, type=2, p2p=0, addr=b8:15:ab:f9:9e:2a
[  426.737749] [AP_WRN] BSS_CHANGED_ASSOC but driver is unjoined.
[  426.756330] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

用以下命令扫描任何无线接入点的过程：

扫描可用的 SSID(AP)

仅获取 SSID 名称

root@TinaLinux:/# iw dev wlan0 scan | grep SSID
        SSID: ChinaNet-kRAH
        SSID: WiFi
        SSID: Programmers
        SSID: \xe9\xa1\xba\xe6\x88\x90\xe5\x8a\xb3\xe5\x8a\xa1
        SSID: ChinaNet-LqFS
        SSID: HP-Print-D9-LaserJet Pro MFP
        SSID:
        SSID: ChinaNet-ffbu
        SSID: 1505
        SSID: ChinaNet-ec7h
        SSID: CMCC-N2AP
        SSID: ChinaNet-ccXn
        SSID: CPE_D24FC1

3.配置连接wifi

wpa_supplicant连接WIFI的时候会从配置文件中读取账号和密码，以及加密方式等，所以我们再运行wpa_supplicant工具的时候要提前写好配置文件。
配置文件名称自定，但是要以 .conf 为后缀，并保存在 /etc/ 目录下，这边给出一个配置文件的例子。
编辑vi /etc/wpa_supplicant.conf 文件:

ctrl_interface=/var/log/wpa_supplicant
update_config=1

network={
    ssid="Programmers"
    psk="100ask****"
}

创建一个socket通信的目录

mkdir -p /var/log/wpa_supplicant

4.连接到 SSID

root@TinaLinux:/# wpa_supplicant -B -c /etc/wpa_supplicant.conf -i wlan0
Successfully initialized wpa_supplicant

5.为 WLAN 接口分配IP地址

root@TinaLinux:/# udhcpc -i wlan0
udhcpc: started, v1.27.2
udhcpc: sending discover
[  602.197655] [TXRX_WRN] drop=1759, fctl=0x00d0.
udhcpc: sending select for 192.168.0.118
udhcpc: lease of 192.168.0.118 obtained, lease time 60
udhcpc: ifconfig wlan0 192.168.0.118 netmask 255.255.255.0 broadcast 192.168.0.255
udhcpc: setting default routers: 192.168.0.1

6.检查连接性

最基本的连通性测试是使用"ping”命令。在此示例中，无线路由器（关联到）的IP地址为192.168.1.1：

root@TinaLinux:/#  ping www.baidu.com
PING www.baidu.com (14.215.177.39): 56 data bytes
