1941W 无线客户端丢失 DHCP IP 地址

1941W 无线客户端丢失 DHCP IP 地址

我正在尝试使用 1941W 路由器通过192.168.1.0\24实验网络“扩展”网络。192.168.10.0\24

我已经配置了 1941W 来分发192.168.10.0\24网络,通过集成的 wlan-ap 0 进行 WLAN 访问,并使用

最初,这种方法运行良好,但几分钟后,客户端会与 AP 断开连接,然后重新连接。发生这种情况时,它们似乎无法“重新获得”租约(Wireshark 显示连续的 DCHP Discover 数据包没有回复)和 IP,但租约仍显示在 DHCP 绑定中。在客户端续订 DHCP 租约没有效果。这种间歇性意味着它与无线有关,但我不太确定。

我发现修复此问题的唯一方法是重新加载 AP,但目前还没有发现任何有意义的变化。任何指导或帮助都将不胜感激!

这体现在dot11 association 在此处输入图片描述DHCP bindings以下: 在此处输入图片描述

我们可以看到客户9801.a7ad.ea73端既有租约又有关联……但没有 IP 地址。

以下是 1941W 和 wlan-ap0 的配置
