wlc2504无线网络网速异常,ping包有丢包现象,在做测速时较明显,下载文件网络速度不稳定。AP有两种2709和1832.AC版本8.5.152.直接连到POE交换机上网络网速正常。已升级过AC微码。现询问可有相关配置案例。附件中的配置有什么问题吗?

先检查一下控制器设置,再查看分析一下是某一个AP的问题,还是所有AP都有问题?可在控制器上查看一下AP的details状态信息。也可通过WLC的命令行看一下AP的详细参数,最后可抓包分析一下。以下命令在WLC上执行分析。
show ap join stats summary all / detailed <MAC>
show ap summary

看描述来说,应该是有线没有什么问题,如果说丢包的话,不排除有无线干扰或者信号强度不足等问题。
对于AP2702和AP1832都是支持802.11ac的,介于目前的情况:
建议确认:
1、AP是什么模式(Local or FlexConnect?)问题是否发生在特定的AP范围内?或某种型号的AP下才会有丢包现象?
2、问题是否发生在特定的终端或某类终端上?
3、可以看一下AP的RF情况。
show ap auto-rf 802.11a <ap-name>
show ap auto-rf 802.11b <ap-name>
show client detail <mac-add>

希望有帮助

AP是Local模式。实测有些点位的干扰有点大,问下有否从配置上的优化方法?
执行AP RF命令结果见附件:
