使用 OpenWRT 和 RPi 创建 AP 但找不到 SSID
Creating an AP with OpenWRT and RPi but cannot find the SSID
我有一个 RPi，我想在其上创建一个 'low user' 强制门户。这在 Raspian 下工作，但由于我需要一些网络路由更改，我也在尝试 OpenWRT。但是我似乎无法进行全新安装以作为 AP 使用。
我安装了所需的驱动程序并且一切正常，但找不到我的任何设备可扫描的 SSID。是不是我漏了什么蠢东西？

同样的问题。 RPi 上的 OpenWRT。
Ralink 5370，rt2800usb 已加载，wlan0 存在，甚至在 Luci 中可见。虽然没有广播 SSID。日志中也没有明显的错误。
已尝试固件版本 22、24 和 29。结果相同。

似乎 modprobe 试图加载某些模块但无法加载。
lsmod 给出此输出（限于提及 rt2800 的模块）。
兼容 1919 3 rt2800usb

似乎是一个错误或（我希望）像 OP 所说的那样 - 我们都缺少一些愚蠢的东西。
谢谢
傻笑
编辑：
显然没有必要寻找解决方案。唯一的办法就是重新编译。
看这里：https://dev.openwrt.org/ticket/17679#comment:11
我有一个 RPi，我想在其上创建一个 'low user' 强制门户。这在 Raspian 下工作，但由于我需要一些网络路由更改，我也在尝试 OpenWRT。但是我似乎无法进行全新安装以作为 AP 使用。
我安装了所需的驱动程序并且一切正常，但找不到我的任何设备可扫描的 SSID。是不是我漏了什么蠢东西？

同样的问题。 RPi 上的 OpenWRT。 Ralink 5370，rt2800usb 已加载，wlan0 存在，甚至在 Luci 中可见。虽然没有广播 SSID。日志中也没有明显的错误。 已尝试固件版本 22、24 和 29。结果相同。

lsmod 给出此输出（限于提及 rt2800 的模块）。

似乎是一个错误或（我希望）像 OP 所说的那样 - 我们都缺少一些愚蠢的东西。
谢谢 傻笑
