路由器偶尔会断网，求诊断

三季稻大法师

各位路过的大佬指点一下问题
型号：RT-AC68U，有一次路由器直接重启了，我拿到机器开机后第二天中午断网，看日志没有头绪，但是显示系统启动时间是断网时间，应该是自己重启了一次，我没有设置定时重启。另外日志有个奇怪的地方，都是一月中间突然多出来一段5月。大概像

后来还偶尔会断网几十秒。不能确定是电信服务商的问题还是路由器的问题。日志没有什么有价值的信息，大概是这样：

我路由器都换了好几次了，真不想再换了

微信扫一扫，阅读更方便^_^

固件版本？ 另外是否可以上传完整的系统日志？

系统启动时间是断网时间，那推断你的路由应该是重启过了，所以在日志中会出现“May 5...”。路由器在启动中，还没有同步NTP的时候，都会是“May 5...”。

至于你没有设定重启时间，但会自动重启的现象，要看你的完整日志后再能判断。

至于你断网几十秒，提供的那段日志，也没找到你WAN断开的相关信息。

你用的是华硕官方的固件吗？

刚刚12点09又断网了一次，日志也是啥也没有(直接没有12点09的日志输出)。我联系了电信的维修人员，说是有过几次断网记录，不能确定是宽带问题还是路由器问题。

我的路由器插移动硬盘之后总会崩溃，表现管理界面为一直loading，有时候超时，有时候1分多钟后显示出来，日志一并打包上传附件了，请各位大佬过目。华硕官方固件3.0.0.4.386_41634

本来准备上传的，但是论坛只能传压缩包。我怕太麻烦没人看。重新传了压缩包日志

你把当前的移动硬盘卸载下来，然后换另一块移动硬盘，格式化后，挂载上去。这样来排除一下。

当前已经是第二块硬盘了，第一块直接坏掉了，格式化都格不动。

第一块硬盘主要是用来当摄像头的存储，download、timemachine，第二块没有download了。

因为看你提供的日志，在重启之前(“May 5...”)，确实少了好多路由器正常进程退出的信息，所以怀疑会不会你的硬盘导致硬件供电有异常，使路由器直接断电重启。

而且断网提供的日志，和USB的应用比较相关，跟WAN的断线连线没有关系。
