网络不定时，每天一断网
本帖最后由 sy6398680 于 2017-12-18 15:47 编辑路由器AC86U，固件使用原版固件或梅林的 ，网络基本上每天一断网，光猫和路由器都换过，还是出现。具体表现QQ会掉线一下立即又连接上，游戏掉线。WAN-Internet Connection页面的Internet Detection已关闭
下面是路由器的日志（截取的是12月15日的日志），掉线时间是20:29分，有这么一条记录LCP terminated by peer，有没有大神帮忙分析一下，看是什么原因？

和你同型号路由器，也会出现这样的现象，不知道如何处理。 WAN-Internet Connection页面的Internet Detection有没有关掉？ 本帖最后由 sy6398680 于 2017-12-18 15:46 编辑

这里是关着的 sy6398680 发表于 2017-12-18 15:38
这里是关着的
那你切换一下Internet Detection模式，因为“LCP terminated by peer”像是ISP主动切断的。 Master 发表于 2017-12-18 15:53

恩恩，多谢！ 晚上回家试试， 刚才也联系了电信的， 电信的说是宽带有个安全保护机制，会48小时左右断网重新拨一次号， 刚才电信的已经把这个保护机制取消了。 86U性能好嗎
