家里的AiMesh系统经常只有几M的下行速度，请大神看看日志

wow0922

我家是RT-AC86U主路由，然后带着AC5300，RT-AC1900P，RT-AX82U一起AiMesh，其中AC5300和RT-AX82U之间的无线AiMesh传输经常不稳定，稳定的时候100M带宽可以跑90M，不稳定时候测速不到5M，就在刚才又遇到了一样的问题，RT-AX82U满信号但是下行速度只有5M带宽，于是我去拷贝了出问题时段的系统日志，希望大神帮我看看是哪里出问题了，之前41994之前的固件没出过这样的问题，不知道有没有人遇到一样的？

家里目前的连接线路如图

wow0922

之前我通常遇到这种问题，就是先点优化，没用之后再去重启RT-AX82U，AC5300，最后要重启RT-AC86U基本上才会恢复正常，但是这样折腾一圈，起码几十分钟就过去了，不知道目前问题出在哪里，希望能找到病根解决问题。

出问题时候测速图就是这样，可见抖动是很高的，有时候还会上百，而正常时候抖动一般在3以内，家里100M带宽正常时候无遮挡也可以跑到90M，5G网下，wifi6正常时候会更稳定一些。

出现异常的时候，有没有观察过AiMesh的拓扑，是不是发生了改变？

在主路由上，把每台节点路由的“首选上行接入点”固定一下，不要为默认的“自动”。

若RT-AX82U下面的无线设备，基本固定，不会移动到其他区域的话，在“无线-专业设置”里面，添加入“漫游阻止列表”里面。

观察过拓扑，在出问题时候没有发生改变，都是保持原先的连接。我之前RT-AX82U的下面的无线设备都是绑定的RT-AX82U，不允许设备连接其他的路由器。我现在怀疑是主路由器哪里出现的问题？因为每次重启主路由后问题消失，比如现在我回复您消息的时候是今天上午主路由我设置的定时重启，主路由重启后昨晚的问题就消失了，但是过几天100%还会再现循环....

若是根因出在主路由上，那照理其他节点的无线客户端应该也有类似问题。

在主路由RT-AC86U上，把每台节点路由的“首选上行接入点”固定一下，不要为默认的“自动”。

若是根因出 ...

我之前设置过首选上行接入点了，RT-AX82U只允许连接楼下的AC5300，因为AC5300是有线mesh最稳定，而且三频稳定，但是现在还是出这样的问题

根据你的图，RT-AC5300和RT-AC1900P之间无线信号弱，是否距离太远

没错 他俩之间信号确实弱 距离也很远 但是这两个信号弱会导致楼上的RT-AX82U下行速度极其不稳定吗？我目前已经把RT-AC5300和RT-AC1900P放在一起了，先把他俩信号搞好了
