问题描述：
WX5540E AC控制器 AP为WA4320-ACN
当前WIFI4的笔记本电脑连接AP无线网络一切正常，WIFI5或者WIFI6的笔记本电脑连接AP网络经常出现无法连接网络，或者连接成功ping网关时丢包很严重。解决办法是将AP重新启动一下，WIFI5或者WIFI6的笔记本电脑也能正常上网络了。各类新旧手机连接网络基本正常。烦请各位技术支持，感谢

最佳答案
scan type active
scan channel all
这两条配置删除，手动划分一下信道功率，看看空口高不高

您好，如何查看空口高不高，请您指导一下，谢谢
精确vlan 不要permit vlan all
可以试试手工划分信道调整功率 关闭RRM自动调整

是哪一条配置信息
是哪一条配置信息
无线网络不稳定，以下是优化要点，请参考：
1、调整功率和信道。
2、有线网络和无线网络使用不同的VLAN来实现广播域上的隔离。
3、关闭低速率的协议。
4、检查上行物理链路、基础网络是否正常。
5、升级无线设备的软件版本到最新。
6、做好无线网络接入的安全设置，避免非法终端接入。
