无线网：AC型号WX3520H+AP型号WA5320，AP全部离线无法上网

sys不常亮，闪烁绿灯。

那ac控制器还能登录吗，ap集体掉线大概率是ac的问题

AC还能登陆，配置信息还在。

Instance 0's port GigabitEthernet1/0/8 was notified a topology change.

最近有做什么改动吗？ping ac管理地址稳定吗？AP和AC在同一个网段吗？console线接AP，看一下AP报啥错误信息？

就只有添加多设备MAC地址，ping Ac很稳定。console线接AP情况如下： Loading file flash:/wa5300-boot.bin.................................... Done.

这是已经正常开机了，从ap上ping ac试试，看看ap注册报啥错误信息？

dis wlan ap all能看到所有AP，connect都是0

正常的，使用好几年了

那就检查链路。

能登陆AC,能ping 通！

POE交换机也正常吗？AP管理地址池正常不？dhcp 便能正常吗？

有光纤到三栋楼，POE不会全部故障的。不熟悉这套设备，可以远程帮忙看看吗，谢谢

可以看看配置
