我有一个 dwlink dwi-131 usb wifi 适配器，我正尝试将其与 buildroot（用于 sama5d2xplained 主板）一起用于 hostadp。
我使用来自 github 的驱动程序： https://github.com/Mange/rtl8192eu-linux-driver
驱动程序可以正常工作，我可以成功连接到我的 AP。但在设备本身上设置 hostapd 失败。我认为这是因为 iw 找不到物理网络设备。但是 ip、iwconfig 和 ipconfig 可以找到它。
我该如何调试它？

答案1
hostapd_cleanup（hapd=0x80110（wlan2））hostapd_free_hapd_data：接口 wlan2 未启动
嗯，我以前也见过类似的消息，其原因通常是：
- 您已有一个作为守护进程运行的 hostapd 服务，请搜索该服务
ps ax | grep hostap
如果正在运行，请停止
sudo /etc/init.d/hostapd stop
然后尝试手动运行 hostapd
sudo hostapd -d /etc/hostapd/hostapd.conf
- 您的设备已被阻止，请检查
sudo rfkill list输出
如果你看到类似
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
运行sudo rfkill unblock wlan
如果硬阻止设置为“是”，你应该多谷歌一下，但首先你应该打开硬件开关
- 您的设备由网络管理器管理，因此请按照说明将其从托管网络管理器配置中移除这里
