求助，软路由下MESH AP模式的断网问题

qiu520 · 发表于 2021-4-25 22:37

网络架构：ESXI，运行OPENWRT，单臂，接交换机（非VLAN），下面再接三个易展TP XDR1850的小音箱路由器做ap,构成MESH网络。
问题是：其中一个次路由AP上班的时候就断电，下班回来后再通电，但往往一通电后，就会弄到所有AP都不能上网，AP获取不到IP,需要用电脑连接网线到交换机，重新拨号才能上网。
已确认光猫已关闭DHCP服务，OPENWRT也设备了强制分配DHCP了，百思不得其解，深深困扰着我，请各位高手指教。谢谢

难道这不是tp的问题？你觉得是软路由问题？

就是搞不清楚啊

搞不清楚就用排除法，先去掉软路由，直接光猫拨号连3个tp，问题还能复现么？还出线就是tp问题，不出现就是软路由问题，这种问题归根到底只能你自己动手去排除，再怎么问大家也只能猜测和建议，最终还是要靠你自己

谁拨号？确定这种接发确定没有广播风暴

断电的ap是不是主要的？mesh中是有主次之分的。
如果用app管理就只能登陆主要的那个，其他的可看到。

谢谢，稍后换个硬路由拨号试试

软路由拨号，这种接法可以正常使用，但当其中一个ap断电后再恢复就大概率有问题

断电的是次路由节点ap

断电的是次路由节点ap

环境差不多，只有两个7650，都关dhcp，双频分离，指定wan口，没出现你的问题。
你可故意停掉另一个ap看看是否还有问题。

3个磊科mg1200AC做AP时，不定时的全网瘫痪，和你这个有共通点么，你可以去磊科板块瞧瞧

测试了几天，貌似解决了，在openwrt里面为ap设置静态ip，测试了两天，ap通电后也不会断网了

还是会出现断网，只不过机率小了点，日志如下，希望有高手帮忙分析一下，谢谢
