Hostapd 不适用于我的一台设备

  • 772

我正在尝试将我的 Raspberry Pi Compute Module 3+ 设置为带有 WiFi 加密狗的接入点的接入点。

我正在关注本教程：https ://elinux.org/RPI-Wireless-Hotspot 。

我可以使用加密狗 EP-N8508GS 设置接入点，但是当我尝试使用 TL-WN722N 时，出现以下错误：

pi@raspberrypi:~ $ sudo service hostapd start
Job for hostapd.service failed because the control process exited with error code.
See "systemctl status hostapd.service" and "journalctl -xe" for details.

这似乎是 nl80211 驱动程序的问题，但我真的不明白为什么它适用于第一个加密狗而不适用于另一个加密狗。我想尝试使用 tp-link 加密狗，因为第一个不支持 AP 模式并在设备尝试连接时使 kernell 崩溃。

    看来您需要 tp-link USB dongle soft-AP 的驱动程序。我通过安装此驱动程序解决了这个问题。你可以找到它：这里
