最佳答案
看链路是不是拥塞，接口下是不是有错包，做流统定位丢包位置

这个是华为AC 的 上连口 统计的流量，华三的S5130上面我创了一个VLAN9，DHCP下发，下连的 华为S2100当傻瓜用，可以获取地址 可以上网，就是ACping会掉包
先排查一下内网看看吧
AP-AC（是否有丢包？）
AC-核心
有线没问题的话 就是无线需要进行优化了
信道 频段这些 发射功率和天线调整等等

AP发射的wifi信号正常上网，获取的wifi ping会掉包，ac ping 也会掉包 如果ping 192.168.0.254 （此ip在华三交换机上，用来做悠闲网络的网关，下连S2100当傻瓜交换机使用） 192.168.0.249（打印机ip） 这个ip就掉包了 80%
有线环境下 也掉包？
S2100 ping 你的上联呢 是否掉包？
C:\Users\77414>tracert 192.168.0.249 通过最多 30 个跃点跟踪 到 bogon [192.168.0.249] 的路由: 1 3 ms 3 ms 3 ms bogon [172.16.3.254] AC地址 2 * * * 请求超时。 应该过一个 192.168.0.254 （华三交换机） 3 * * * 请求超时。 4 * * 4 ms bogon [192.168.0.249] 打印机地址 跟踪完成。
怎么我感觉线是你的vlan 或者路由没互通呀 内网环境都到不了 外网正常 就是内网问题了 有远程的话 可以协助你看一下
你掉了 哥们
