即使 wifi dongle 设置为默认值，Linux 在插入时也会开始使用 4G dongle

我有一个远程树莓派，运行着一个无线适配器。我只能通过 SSH 访问它。每当我要求父亲连接 4G 适配器时，我就无法再访问 pi。如果删除，一切就会重新开始工作。似乎所有内容在插入后都会路由到 4G 适配器。

这是插入加密狗之前的输出：

ip route list
default via 192.168.1.1 dev wlan0  metric 303 
169.254.0.0/16 dev docker0  proto kernel  scope link  src 169.254.41.13  metric 204 
169.254.0.0/16 dev veth1005631  proto kernel  scope link  src 169.254.175.70  metric 206 
172.17.0.0/16 dev docker0  proto kernel  scope link  src 172.17.0.1 
192.168.1.0/24 dev wlan0  proto kernel  scope link  src 192.168.1.161  metric 303

事情应该wlan0默认。有人知道发生了什么吗？

我认为加密狗配置为使用192.168.1.1.会不会有问题？

您有什么想法可以远程缓解这个问题吗？
