USB WiFi适配器保持断开连接？

我有一个无头的Fedora Linux盒子，我正在尝试使用Alfa AWUS036H USB无线适配器。我正在尝试连接到自己的无线网络（由ISP提供的Actiontec路由器）。无线信号似乎很强（任务栏小部件显示4/5小节已满）。

使用VNC桌面会话，输入WPA密码后，它会工作一段时间，然后几分钟，连接断开，我可以在桌面上看到网络指示器返回到“旋转”图标，并且最终弹出一个身份验证对话框以重新输入WPA密码，但是重新输入它不起作用。

看一下dmesg日志，我看到：

您可以在前五行中看到该wlan0接口已成功向路由器进行身份验证。但是过了一会儿，“没有来自AP的探测响应”，似乎正在尝试建立自己的无线网络，寻找开放的WiFi通道？然后，它尝试重新验证路由器，但失败了，几分钟前它成功了。

从这些日志中，是否是IPv6广播使我的适配器掉了？还是“由于不支持WMM / QoS而禁用HT”？

“无探测响应”仅等待500毫秒来等待服务器的响应。是否可以在某些地方的某些配置中增加该值（我的路由器是否响应缓慢）？

编辑：在路由器端的更多详细信息：这是一个运行固件TDST2200H-31.126L.04的Actiontec T2200H。我注意到路由器的Web界面是一件奇怪的事，它声称其MAC地址为10：5F：06：E2：96：EC。这与Linux客户端上的日志记录相差一个数字（日志显示最终分组应为“ ED”，而不是“ EC”）？无线安全设置为WPA / WPA2-TKIP + AES。启用WWM，禁用WWM省电。

家里的其他使用PCI无线卡的计算机都可以正常连接。这仅仅是因为Alfa USB适配器无法处理WMM或IPv6命令吗？
