RT-AC86U断线且重启无效

maoyiye

求助！各位大佬
我这台RT-AC86U已经找京东换过两回了
刚开始三个礼拜用着还好
今天半夜突然就中断，且重启之后无法重连
光猫无线有线均正常，排除光猫及网络的问题
只有可能是因为路由器抽风了，且重启无用
之前为了防止断线，特意将参数设置成客服推荐的那一套
结果这玩意儿跟我前几个还是出现一样的问题
附上最近几行日志给各位大佬看看这是什么问题

我知道有很多朋友有同样的问题，可是我真的找不出一个完全彻底的解决办法

用的哪版官方固件？

注意到你提供的日志中出现“pppd[1422]: Timeout waiting for PADO packets”，你的RT-AC86U在尝试拨号，但ISP没有回应。你的光猫是不是也拨了PPPoE？
