Configuration OpenWrt：如果STA失败，AP将停止

我有3个接口：

• 局域网（WiFi AP、DHCP服务器）
• wan（WiFi站、DHCP客户端）
• wan2（以太网、DHCP客户端）

我安装了

mwan3

，因此，使用此配置，我应该通过wan和wan2访问Internet，如果只有一个在线，则只能通过两者之一访问Internet

我试图在每个界面上模拟一个

ifdown

事件，但我仍然可以通过另一个界面访问Internet。我还尝试禁用

WiFi STA

接口，一切正常

但当我关闭与

WiFi STA

对应的WiFi源时，

WiFi AP

停止，我断开了连接（有时WiFi AP会重新出现几秒钟）

编辑： 这里有两个系统日志。。。 当我从OpenWrt设置手动禁用Wifi客户端接口时，一切正常：

当我关闭Wifi客户端源时，它会坏掉：
