Raspberry Pi 4 上的 OpenWrt 不支持 AC 和 80MHz

Raspberry Pi 4 上的 OpenWrt 不支持 AC 和 80MHz

所以,我从互联网上收集了如何将 Raspberry Pi 4 设置为 OpenWrt 路由器(接入点,无论你怎么命名)的信息。我很高兴地说我能够使 WiFi 工作并从 iPhone 连接到它。呜呼。到目前为止,这是我想到的 -https://docs.google.com/document/d/e/2PACX-1vQ2lDbAXV3b2Fzw9-LC7PRkirLQGqRH-iLm6cNcUz_b4lawJG_-57yWQKrYrbO8awSCcY_koax8os2e/pub(抱歉格式笨重,我是在测试时输入的)。一切都很酷,它可以工作,但是有一个问题。它似乎无法进入 AC 模式和/或 80MHz 频段。走后"htmode": "VHT80"网络似乎消失了。VHT20并且VHT40似乎工作正常。另外,尝试了一些其他频道+VHT80组合,但无济于事。

也许有人对此有更多的运气,或者这是 Pi 当前固件的限制?

我正在 2020 年 5 月 8 日的最新快照图像 ( ) 上对此进行测试openwrt-bcm27xx-bcm2711-rpi-4-ext4-factory

感谢您的任何意见!
