我的路由器用着用着突然就掉线了，求系统日志解释

spider

我的华硕路由器用着用着突然就掉线了，观察系统日志，如下这段比较可疑，所以截下来。

请大家帮忙看一下，掉线是因为什么情况引起的？

这个看起来是账密错误了.是否账密有被更改掉?
或者是猫宕机了,重启猫看看,路由器拨号没有得到服务器端的正确回应

你的情况其实和我的一样，华硕路由器很多出现这样的情况，至今未能解决,台湾华硕论坛很多用家反映这个问题。参考我之前帖子：http://net52.cn/thread-2575-1-1.html

涵哥

看到你的日志，第一行就知道原因了，WAN Connection: Ethernet link down.
E口挂掉了。所以导致后面的验证都是失败。先检查一下线路吧

有事您说话

可以先检查你的路由器WAN端物理连线是否完好，如果没有问题的话，再看路由器上的的Modem是否出现异常，
