重新设置功率和信道后，故障缓解。等一段时间后，故障重现。

我把AP转换成瘦AP，在WLC上检测到：

2.4G信道11的干扰比较严重；有条件的情况下，最好的办法就是用5G，以避开干扰的影响。
通常建议用户做一个site-survey， 看看干扰是否是因为AP放置的位置不对，造成了严重的同频干扰。或者，使用Spectrum Experts等频谱分析软件找到干扰源，然后干掉它。如果是一些外在的，用户所不能操控的干扰源，比如电信基站等，那就没别的办法了。

结合LOG和临时解决办法来看，
我认为很有可能是因为这个AP附近存在着干扰，2.4G的可用信道资源受限，导致客户端的连接不稳定。

按这种情况，除了使用5Ghz，还有什么办法？
