我已经努力让 hosapd 工作一段时间了。
我所遵循的指南将附在底部。
所以首先要做的事情。
据我所知，我的网卡确实支持 AP 模式。如果不正确的话，请纠正我。

因此，我跟随本指南然后发生以下情况。
网络已创建，可以从多台计算机查看：Windows、Mac 和 Linux——以及我的一些手机。
但是，问题是，没有一台机器可以连接到它。
我的 Mac 和 Windows 7 机器都在那里停留了大约 10 秒钟，然后超时。我的 iPhone 尝试加入但从未建立连接。
澄清。通常，即使热点出现网络问题，我的机器也能加入，然后它们会为自己分配一个 IP。169.xxx
但是，它们也不会这样做。
这可能是驱动程序问题吗？

答案1
问题出在 rtl8192cu（驱动程序）上。它目前无法正确支持 AP 模式。它似乎可以工作，显示设备处于主模式，但您不会收到任何信标或流量。
阅读此主题 -http://www.spinics.net/lists/linux-wireless/msg96070.html- 希望开发人员能够发现缺少什么，以使 AP 模式正常运行。
