RT-AC87U使用过程中会突然掉线，重拨的时候，提示“网线未连接”

然后重新插拔了一下RT-AC87U WAN端的网线，但仍旧会提示“网线未连接”

截了一段系统日志，如下：

请问是什么原因呢？是RT-AC87U本身硬件的问题，还是固件问题？

固件版本多少

硬件没啥问题，看你的log都是在拨号，然后失败
Sep  8 06:34:37 pppd[9178]: PAP authentication failed
Sep  8 06:34:43 pppd[9178]: Connection terminated.
Sep  8 06:34:43 pppd[9178]: Modem hangup
就最后一次是成功的，而且还是私有的WAN IP。

建议检查一下物理连接看看
