OpenWrt 断网记录及原因分析
大致情况
某天晚上使用平板访问 emby 服务, 电影看了一小半, 发现卡住了
随后便发现网络也断了, OpenWrt 无法 ping 通, 管理页同样无法登录
想着等它自己恢复以便查看下系统日志, 没想半个多小时还是没法访问的状态
最后只能断电重启
隔天同样经历多次断网再重启的烦人经历, 后 这里不知道具体做了啥网络操作了... 发现也会有网络断掉但是 OpenWrt 还能被访问的情况, 这时只需重新点击上网接口的“连接”即可恢复网络
可能原因
目前判断或许是
访问emby导致
但是 emby 跟其它大流量服务有何区别呢?
网上找到类似的帖子(关于N1断网的折腾记), 但是貌似也没说出啥二六十二来
至少目前来看, 恢复网络正常后, 没有访问 emby 服务, 目前运行正常
