RT-AC86U 2.4g失速

wolf94

昨天早上起来，发现2.4g网速极慢1m（家里是200m，2.4g平时测速60-80m）。于是重启，重启后完全没用，速度更低。只能刷固件，初始化，降到21140，设置好后2.4g网速依然1m，有时15m，换网络通道也没用，大家看看什么问题，是硬件坏了吗？

看看无线日志，日志发上来看一下

是不是所有无线客户端都有这个问题？

尝试调整无线高级页面的调制方式选项看看

是不是所有无线客户端都有这个问题？

是的，手机、游戏机、笔记本，都出现低网速问题下面是同一部手机，相同位置、连续测速的结果

尝试调整无线高级页面的调制方式选项看看

昨天三种都测过，结果没有变化

之前一直很好，什么问题都没有，直到9.9。唉……2，3还没遇到，算是幸运
