RT-AC68U崩溃了一分钟断网一次又自动连接

zhfnzh

现象：有线连接和wifi连接都是一样的毛病，浏览网页一会很快，一会就慢，感觉一分钟左右就得断网一次，然后自动连接。
买的美版的，一年半了。之前用的X7.7的固件。一直没有问题。10月13号晚上10点左右突然网络就不好使了。之后我就刷了很多固件X7.2 / X7.9 / X7.5等等，一直解决不了。我直接网线插光猫拨号用起来是没有问题的。光纤连接是PPPoE模式的。

哪位大神给解释一下啊。我是怀疑路由器坏了 。

一度怀疑是路由器的问题，所以我重新买了新的tplink的路由器。并16号晚上19:00点安装成功，网络完美运行几分钟之后又不行了，还是一分钟断网自动连接。然后tp和光猫全部复位重启等了，还是不行。因为tp的路由器没什么好设置的，所以我也就没再动。凑活着用了，至少每分钟还有个几十秒是能上网的。但是不知道为什么，突然晚上23:30的时候发现网络正常了，很顺畅了。然后17号早上再试试网络还是没问题的。这我就更奇怪了。怎么就突然好了呢。  后来联通的给我打电话，说是让我mac克隆就好了，那意思都懒得上门了。所以今天晚上我回去先看看是不是网络还是正常的，如果正常我再换上我的华硕继续试试。如果网络不行，我就mac克隆，如有问题我再找联通。

现在说一下结果啊，晚上我回家之后网络还是正常的，然后换上华硕路由，什么都不用设置，插上网线之后网络直接就能用了。哈哈。包括所谓的mac 克隆我也没有设置。目前为止已经用华硕平稳运行了2天了。具体这次折腾我3天的网络问题，以稀里糊涂结束的，反正我是找不到原因，但是可以肯定的是绝不是路由器的问题，所以应该是联通宽带的问题。或许真的跟那个联通师傅说的是mac问题，但是网络正常了我也无从重新设置去考证了。谢谢大家的关注和回复。感谢。

观察了你的log，基本发现了问题所在

以上的log表明，第一行的时候，在账密验证的时候，就直接失败了。(这边一个疑问，一般运营商都是chap验证，为啥你这里是PAP，不知道是你的固件问题还是运营商设置)，这个你可以和运营商确认，
log第三行是路由器发送PADT的包，这个时候，由于验证失败，路由器就会发送这个包请求断线。

大体的过程和你讲清除了。接下来和你说一下，尝试解决的方法

1.固件方面的问题，可以使用官方固件，升级之后直接使用硬体初始化，
2.网络被入侵，路由器被操纵，发送假的PAP认证，这个时候，ISP使用CHAP的，所以肯定是失败的。这个需要你确认一下当前网络环境安全，然后再试
3.运营商的限制，也就是说运营商还是PAP的认证，但是路由器由于固件的问题，出现断线了。之前有些ISP有一个保护机制，就是你在较频繁断线之后，会在短时间之类不让你再次连接。即不接受认证对比，然后导致失败
4.运营商的路由器管控，可能是运用商管控AP，当然这个情况现在很少了。如果这样的话，可以使用WAN设定页面的MAC clone的方法解决
5.网络侦测方法有问题，路由器端的网络侦测建议调整为不同的选项，有些地方，如果是ppp echo的话，ISP的设备不会响应。可以调整为DNS probe试试看

大体就是以上这些，你可以试试看，如果再有问题，可以继续讨论

美版进来都是返修的居多，您可以先尝试涵哥的建议排除看看

个人建议先刷回之前稳定版本的固件使用看看。
刷完固件之后按压路由器外壳上的Reset恢复出厂值，重新设置。

谢谢涵哥给解答。刚刚联通的说让我MAC clone试试。今晚上回去试试。另外说一下。昨晚上我安装了新的tplink路由器，19：00点安装完网络还是不行的。但是不知道为什么晚上23:30的时候突然发现网络好了。今早是试试网络也是正常的。今晚上我在回去试试是不是正常了，然后再重新换上我的华硕再接着试。哈哈。

我都不好意思说。什么都没干，网络是自动好的。现在已经正常了。我怀疑就是联通的问题，跟我路由器没关系。呵呵
