我们在客户所在地(一个大大厅,大约 200 英尺 x 150 英尺)的生产环境中面临 WiFi 连接问题。细节:
环境:
- 4 个 Cisco WAP4410N 接入点安装在大厅的柱子上
- 所有 4 个 AP 都配置为相同的 SSID、相同的频道(即 6 个)
- 两种移动设备
- 摩托罗拉 MC55 - Windows 移动操作系统 6.5
- Urovo i6300 - 安卓 7
- Chainway C70/C71 - 安卓6.0
- 用于上述所有设备的软件应用程序都是基于 TCP/IP 套接字的。消息不断地发送和接收。消息大小约为 KB。
- 没有为任何 AP、交换机甚至服务器启用 DHCP。上面提到的所有移动设备都配置了静态 IP。
- 服务器在 SUSE EL 11 上运行
问题:在平台漫游时,MC55正常工作,几乎没有断线(假设没有丢包)。但是在漫游时使用 Android 设备,我们会遇到中度到严重的连接问题和数据包丢失。
请帮助我如何解决这个问题。
我在下面分享了 AP 配置详细信息:
