1.使用WIFI实现上网
100ASK_V853-PRO全功能底板上板载有全志XR829，烧录的开发板系统已经进行了适配，可以直接使用，在开发板上输入ifconfig，可以显示已经使能的网络设备。

可以看到wlan0默认已经使能了，如果没有使能可以输入ifconfig -a,查看所有网络接口是否存在wlan0设备，如果存在wlan0，则可输入ifconfig wlan0 up使能wlan0。

使能完成后，由于系统内置wifimanager-v2.0，可以使您快速实现配网，输入wifi -h，可以获得参数帮助

接下来可以进行扫描wifi，注意扫描前需要检查天线是否安装好，安装位置如下图所示。
检查安装完成后，在开发板的串口终端输入wifi -s
root@TinaLinux:/# wifi -s

扫描完成后会打印Wi-Fi scan successful和所用的时间time，可以看到输出信息中的ssid为扫描出来的WIFI名称，注意WIFI名称如果是含有中文字符可能会无法显示。
接下来可以进行连接WIFI进行上网，输入wifi -c ssid [passwd]，其中ssid为WIFI名，passwd为密码
假设我现在连接的WIFI名称为100ASK，密码为12345678，则需要输入wifi -c 100ASK 12345678
root@TinaLinux:/# wifi -c 100ASK 12345678

可以看到当我们输入完成后，开发板会自动连接到WIFI并会自动获取IP地址，此时我们可以执行ping www.100ask.net，测试wifi是否可以ping通百问网的官方网址，按下Crtl+C结束测试。

2.使用有线网卡实现上网
对于有线网卡，我们在我们的补丁文件中已经做了支持，但没有默认使能，需要我们手动进行使能，在开发板的串口终端输入ifconfig -a查看所有支持的网络设备，我们可以看到输入后会出现eth0有线网卡的设备。
root@TinaLinux:/# ifconfig -a
eth0 Link encap:Ethernet HWaddr 92:A8:E0:01:3D:F9

确认eth0有线网卡的设备存在，此时输入ifconfig eth0 up，使能有线网卡。
root@TinaLinux:/# ifconfig eth0 up
[ 3183.253385] libphy: gmac0: probed
[ 3183.302411] sunxi-gmac gmac0 eth0: eth0: Type(6) PHY ID 001cc816 at 0 IRQ poll (gmac0-0:00)
[ 3183.322880] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
此时从路由器上引出一条网线，插上开发板的有线网口处。
当网线插入开发板后，开发板的串口终端则会输出以下信息，表示有线网络已经连接成功
root@TinaLinux:/# [ 3318.532310] sunxi-gmac gmac0 eth0: Link is Up - 100Mbps/Full - flow control rx/tx
[ 3318.540797] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
此时需要为开发板设备的有线网口获取IP，输入udhcpc eth0
root@TinaLinux:/# udhcpc eth0
udhcpc: started, v1.33.2
udhcpc: sending discover
udhcpc: sending select for 192.168.1.38
udhcpc: lease of 192.168.1.38 obtained, lease time 86400
udhcpc: ip addr add 192.168.1.38/255.255.255.0 broadcast + dev eth0
udhcpc: setting default routers: 192.168.1.1
此时我们可以执行ping www.100ask.net，测试wifi是否可以ping通百问网的官方网址，按下Crtl+C结束测试。
