RT-AC86U AP模式 AiMesh无线组网不稳定

lynxiaojing

两台RT-AC86U无线组网，一台RT-AC1900P有线组网。主路由为RT-AC86U，操作模式选择：无线接入点（AP）模式 / AiMesh 路由器（AP 模式）；手机连接到RT-AC86U AiMesh Node的wifi时会出现间隙性不能上网的情况。

具体表现为手机不能上网，浏览器不能直接访问主路由，10秒左右后恢复。已关闭漫游助手和smart connect。

固件为官方最新版32799，也试着恢复过出厂固件20467，重置，reset nvram这些都试过，两台RT-AC86U做主路由也都试过，都有上述情况。

据观察出现这种情况时会有wds日志，wds为默认设置，未修改过，wds日志一直存在，相关日志如下：

楼主意思是，wifi client切换至AiMesh Node一瞬间发生断连现象，还是wifi client连线AiMesh Node之后，会经常发生client断连？

wifi client连线AiMesh Node之后，会经常发生client断连，wds日志每天都有这么多，正常吗

应该不算是断连，wifi没有断开，但是wifi client不能上网，不能访问主路由，怀疑AiMesh Node和主路由间的连接出了问题

这段日志应该是说：AiMesh主路由轮询节点路由是否在线。

先收敛一下问题，

1. 主路由RT-AC86U的有线客户端PC，持续ping节点路由RT-AC86U的IP，有没有断ping？也频繁断ping的话，证明你的RT-AC86U和RT-AC86U无线组Mesh网络，本身就不稳定。这个时候就要看一下，你周遭的环境是不是有干扰，是不是拉近一些主路由和节点路由之间的距离，主路由和节点路由的天线角度尝试调整一下。

2. 上面第一点正常的话，主路由RT-AC86U的有线客户端PC，持续ping节点路由RT-AC86U的有线客户端PC，仍旧正常的话，那问题出在节点路由和wifi client之间。既然你之前已说了，组建Mesh之前，已将Smart Connect和漫游助手已关闭，那你再调整一下无线设置页面里面的调制方式，把无线传输公平性关了之后，再透过无线方式添加节点路由，看看问题有没有改善。

好的，我找时间试一下，client无法连网的情况一天出现那么几次，不是太好测试
wds日志是在ap模式下才出现如此频繁吗，路由模式下貌似基本没有？
