AX1800端口频繁断连

jinnrry

现象：用着用着突然网络就断开了。

Case1:

自编译[LEDE的AX1800源码]，用一段时间后内核日志中频繁出现

1. eth1: PHY Link is down

复制代码

Case2:
使用[官方最新系统4.1版本镜像]，用一段时间后依然会断连。内核日志：

如果换个网线还有这样的现象吗？

如果换个网线还有这样的现象吗？

排查了好几个月，刚开始以为是我编译的固件有问题，我换了好几个固件，还有官方的固件，都有问题。

然后我以为是我网线的问题，我又换了网线，再之后又尝试了不用网线，用wifi，始终都有问题。

最近突然发现，如果是电脑上开pt服务，存在大量连接以及大流量上传下载的时候，这个问题会变得非常严重。甚至1分钟不到就断连了。如果我把pt关了，断连就没那么频繁了。

于是我有怀疑是光猫性能问题，我把路由器去掉，电脑直连光猫，结果问题不会出现。所以这是路由器硬件有问题？我看路由器全程cpu、内存都没占满，温度也没有异常

我还怀疑过是我装的插件有问题，我编译的时候把所有插件都去掉了，仅保留最最基础的路由相关功能，依然有问题

pt服务用的啥软件，我们这边可以试试
