MT-1300 不定期 WiFi 中断

twotreeszf

更新：
关闭Macbook网络唤醒后，问题解决，不会重连WiFi了。


以下为问题描述，希望官方能帮忙排查解决一下：


系统：官方原版 3.211 环境：安装 Luci
WiFi：5G + 2.4G

问题描述：
发现会不定期 WiFi 中断，一般几个小时一次，一天好几次。因为每次WiFi中断会自动重开，一般是2.4G的热点先出来，电脑头一天下班时，连得5G，第二天早上上班就变成2.4G了，说明晚上断过。正常使用过程中，也发现过WiFi中断，表现为SSH后台突然不能敲字了，然后发现WiFi连接没了。

执行下面命令再观察一下

1. /etc/init.d/gl_health stop
   
2. /etc/init.d/gl_health disable

复制代码

好的，我试试

是不是有啥东西把内存都占光了啊？

twotreeszf

内存问题我再观察一下，按理说不应该，晚上都没有流量。

请教一下，这个机器我这边还有个问题，就是没法刷自己编译的OpenWrt固件，要么完全没法启动一直闪灯，要么只能ssh进去，但是luci没有，而且我看dmesg有报错，麻烦问一下怎么回事，用的这里的固件 https://www.right.com.cn/forum/f ... wthread&tid=7085123：

更新一下关于WiFi断开的问题，今天在公司加班，突然发生了断开和5G切到2.4G，我查了一下路由器日志，发现比较正常，于是看了一下Mac电脑的wifi日志/var/log/wifi.log，在日志中发现这么一条，时间点刚好吻合，目前猜测是Mac系统的问题，我暂时关闭了电脑的网络唤醒，再观察一下。

看起来像是系统休眠导致的

twotreeszf

我系统并没有休眠，貌似是系统bug，在正常使用过程中被触发网络唤醒，导致了重新联网

更新，这几天没有观察到中断，后面再看看，多谢。
