Ubuntu 12.04.2，3.2.0-49-generic，来自 saucy 的 x64 hostapd（hostapd_1.0-3ubuntu2_amd64）
已经尝试过精确更新，但无济于事。
您可以在下面的调试输出中看到，hostapd 将 EAPOL-Key 请求发送到客户端，但没有收到任何回复......
我试过了：
- 仅限 WPA
- WPA + WPA2
- 从 0.7.6 开始的多个 hostapd 版本
我尝试连接的站点是一台笔记本电脑 (w7) 和一部 iPhone 3S

答案1
几天前，我遇到了与 hostapd_1.0-3+b1_armhf.deb 类似的问题，当我在我的 ap（raspberry pi）上设置 wpa 时，即使密码输入正确，连接也总是通过密码验证失败。
尝试了较新的版本（hostapd_2.1-0ubuntu4_armhf.deb）后，问题消失了。我不知道这个问题的原因，看起来是由 hostapd 本身引起的，而不是你的配置。
您可以尝试较新版本的 hostapd，希望它能在设备上运行。
