MT2500偶尔断流

xyc9121993

目前是MT2500接光猫，小米AX6000接MT2500开中继模式当wifi。
平常用着没问题，就是偶尔会断网，有时候自动就恢复了甚至感觉不到只是在MT2500的管理页面里看到wan口是离线。有时候就不行，要自己去拔插一下网线重启下之类的才会恢复。
换过一根网线，换完之后有半个月没断过，然后又开始偶尔的断网。
这种情况是什么造成的？
附上部分系统日志，太长了我截取部分看起来跟状态改变相关的部分：

看看光猫的型号呢，重新插拔网线就立即好了吗，还是说必须重启mt2500呢，需要重启光猫吗

光猫的型号。。。就是电信装网的时候配的那种，我APP上看叫天翼5CA2，品牌: SDNSDN，型号: SDN20XX。能恢复的情况是一般我拔插一下网线就好了；不过我有时候也会干脆都重启一下。

能提供更多的信息嗎？

比如说啥，我把光猫的型号啥的回复给楼上了

看log像是mwan3引起的，看下你多WAN那边的配置呢

nyin

毫无疑问就是Mwan3引起的，直接修改mwan3的配置就可以了

Zhijie

我也突然会断网，只不过是我在打游戏的情况下，不清楚什么情况。

萝卜大侠

看上去是多WAN检测的问题，可以在这里将多WAN配置关闭试试

好像没解决，很奇怪。而且关掉之后就看不到这个wan口的联网状态了，现在断网都看不出了= =

有没有尝试过更换网线呢？
