用户被抛出网络而没有任何线索。它们与自主AP (Cisco Aironet 1602i)相连。

Question

这是大楼三楼和四楼的一个小场地。我们在三楼部署了三个AP，在四楼部署了两个AP。此外，配置了一个新的AP，但尚未在第四层设置。在4楼没有问题，但在3楼。

注意:现场调查不是由以前的工程师谁设置的。

AP1和AP3工作得很好，但是AP2有问题。AP2附近的用户虽然接近AP，但连接问题有限。所以认为可能有一些干扰，并断开了AP1。发现它对所有用户都运行得很好。尽管有时用户会被赶出网络。尽管如此，一些用户说，四楼AP正在连接，并发现工作良好。

大多数用户使用MAC。802.11b/g客户端。

只配置单个SSID "KPH-3 SAL“

交谘会的支持建议在无线电接口0上这样做。

这是我的配置

请给我一些建议来解决这个问题。

Answer 1

在这个问题上，我不同意交谘会的意见。跑那么低的速度真的不是个好主意。我不会运行低于12，除非你绝对需要11b。

如果你有干扰，你要找到它的唯一方法就是使用某种嗅探器或频谱分析仪。也许你能借一个？

试着关掉你的无线局域网，看看你能接收到什么其他的无线电信号。你可以在附近找微波炉。您也可以尝试改变频道，看看这是否有帮助(从1、6或11中选择)。
