上海电信最近频繁断线可能是什么问题？
最近频繁断线，已经让电信小哥帮忙换了SDN光猫，还是改成桥接，路由器拨号。刚换好一两天还好，今天又来了。自己的路由器也换过了，问题依旧。日志显示，光猫挂起，然后重新拨号，能够获得同一个IP地址。我的这个配置用了好多年了，最近才发生这种情况的。Mar 25 18:22:50 EdgeRouter-X-5-Port pppd: Modem hangup

顺便提一下，我的WAN口是接在eth4上的，但是，换了新光猫后，端口在auto negotiation的时候会失败，要手动调节成100/FULL，又没得选1000/FULL，eth0就没有这个问题。 我能重现这个问题了，就是打开智能电视，播放在线视频的时候，问题就出现了，光猫就挂起了。 十指剁光 发表于 2024-3-26 13:16

光猫挂起 那应该是光猫的问题
我以前用中兴的光猫就会挂起
换成华为的正常 直接联系电信的人换光猫，或者一步到位，小黄鱼上买个2.5g光猫，让人家配好，色色一一 北区电信，uptime 125天。。 我的也是一直掉，然后我干脆加了一条联通 本帖最后由 十指剁光 于 2024-3-27 00:00 编辑

这个应该是光猫发送了PADT的意思，然后就断线了。可是，这个断线的点是随机的，后来测试，跟我的电视也没关系。已经换过光猫了，应该不是猫的问题。我家只能进一根光纤，早就想多拉一根移动了。 我前几周也出现过这类问题，后来通过手动拨号解决 更新：
最后，换装移动宽带，解决问题。但是，也带来了更多的新问题，比如：没有公网IPV4，DDNS等等。最重要的问题，防火墙设置，IPV6把内网电脑是不是都暴露在网络上，不知道风险大不大。总之，现在网是不断了。
