====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。
Widora AP scan.

===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"
