背景

目标：在一个接口上创建AP，并允许另一个接口作为站。

设置：

--> = Packets to/from
AP --> station --> INTERNET
wlan0 --> wlan1 --> INTERNET

设备）：

Raspberry Pi 3（板载芯片 = AP）
TL-WN725N（车站）

问题

HostAPD 将无法启动。

答案1

下载并运行以下脚本sudo：

pifi.sh：https://github.com/NicholasAdamou/PiFi/raw/master/pifi.sh

这是我为解决上述问题而编写的脚本。

我该如何修复它？

HostAPD 二进制文件没有我所使用的无线适配器的正确固件。

上述脚本将允许您将 aa 设置Raspberry Pi为PiFi Wireless Repeater。
