反复排查了家里所有线路，都是用料比较好的六类线，交换机和网卡也都上了 2.5G 。后面甚至更换了路由器，也给光猫加上了风扇也没有解决，在此期间也试过将 114DNS 改成阿里 DNS 。最后调出家里服务器上的服务的脚本日志，以及华硕路由器日志后发现是电信那边的问题造成的断流。

几乎每隔 2 个小时断流一次，有段时间的高发时段是每天的凌晨 2 点到中午 11 点左右。不知道是电信那一头线路问题还是网传开了梯子导致的断流啥的（家里有台服务器为了做种，专门在 Linux 上开了个 Clash 来防止 qBittorrent 刷新 RSS 时失败）。

测试了光猫的光纤对信号损耗，测试结果发现线材没有问题。感觉是光猫的性能对连接数的影响了，或者是电信那边限制了什么参数（望天
