最近一周，K2P,K3C频繁断网，大家帮我看看什么原因

apple505

上周开始（之前完全没问题），全部连接的设备会突然断网（包括无线，有线），几秒后陆续重新链接，时不时的又这样来一次，宽带是电信的。一开始是K2P，然后换成K3C依旧。后来为了测试是不是运营商的关系，换成移动网络和猫，又把去广告关闭，均依旧时不时的断网。固件均是A大官改的最新版。各位大神帮忙看看什么原因？
设置里的日志如下：

我的K2也是频繁断网

shenjiajun

首先请描述具体断网症状 右下角网络标识变化 ping内网 外网情况

xpader

我告诉你，不要用最新的固件，官方的固件有多新就有多坑。

日志显示没问题，看看dmesg吧

就是断网，像路由器重启一样，全部设备掉线，然后有隔了几秒钟重新连接，右下角么，断网的标识，ping内外网么，断的时候（根本来不及ping,几秒钟就重连了，又能上网了），能体会到这样玩游戏的痛苦吗

这种故障和宽带运营商没有关系，就是路由这边的问题，检查固件版本，K3C最新官改我没试过，旧的1.0只要不重启可以持续正常运行，1.1好像也没有人反馈这个问题，K2P B1版本官改用过没有问题，A1A2不用官改，都是直接刷的华硕，检查220V市电是否电压异常，上下标准在210-230最稳定，路由周围是否有能发出电磁辐射的干扰物，设备尽量使用5G网络。

另外也可以考虑重新按照教程刷一次系统，刷完先恢复出厂一次

K2本身就有断流的通病

zhhf2010

你这问题一般是路由器的问题，运营商你也换过没问题的，可以再去换一下别的非智能的路由器试一下，比如几十块的货，试一下是不是线路的问题，我觉得固件没问题啊，我的没出现这样的问题，再者正常的话没必要去使用最新的固件，只要稳定好用或者够用就可以额，老版的固件不一定不好
