wifi
唠叨几句
MT7688这类“路由器”SOC最大的强项还是网络上，互联效果比普通SOC好很多，这一节讲讲常用的WI-FI操作。
扫描周围AP列表
aps命令运行之后大约5秒，在控制台打印扫描到的结果。

让MT7688通过WI-FI联网
wifimode apsta ssid key命令，ssid和key分别是你的家庭Wi-Fi用户名和密码。

看到了APCLI LINK UP，那么WIFI就连接上了。
检查是否链接好上级AP
ap_client命令用来检查是否连上上级AP，返回“ok”代表已经连接好，否则返回"no"
root@Widora:/# ap_client ok root@Widora:/# ping qq.com PING qq.com (125.39.240.113): 56 data bytes 64 bytes from 125.39.240.113: seq=0 ttl=47 time=7.877 ms 64 bytes from 125.39.240.113: seq=1 ttl=47 time=13.103 ms ^C --- qq.com ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 7.877/10.490/13.103 ms root@Widora:/#
检查有哪些客户端连接了Widora
有时，想要看有多少设备连接到Widora的WI-FI：
