如何在自主模式下启用或绑定 Cisco 3502i AP 上的 80MHz 信道？

我有一个 Cisco AIR-CAP3502I-A-K9，使用 F/W ap3g1-k9w7-xx-153-3.JF5，处于自主模式。我尝试了所有能想到的方法（谷歌不是我的朋友）来配置 5GHz 无线电以使用 300MBps？我可以使用此 CLI 命令配置其他通道：

速度 6.0 9.0 12.0 18.0 24.0 36.0 48.0 54.0 m0. m1. m2. m3. m4. m5. m6. m7. m8. m9. m10. m11. m12. m13. m14. m15.

但我在速度测试中得到的最高速度约为 27 Mbps，使用 iPhone 7 plus，只有 2 个客户端连接到 AP。

我也关注了以下 Serverfault 页面，但也没有成功——是的，这是我发布的一篇文章，当时它“似乎”有效，但实际上并非如此： 在 Cisco 3502i 上启用 300Mbps 的正确方法是什么？

那么我遗漏了什么？

我的带有掩码字段的 AP 配置如下。

接口Dot11Radio1
信道宽度40以上

您已将 5GHz 无线电配置为 40MHz 信道宽度。

通过速度测试获得的实际速度与无线 PHY 速度将有很大差异。
