Ubuntu 16.04 无法连接 WiFi

我已经使用 Ubuntu 16.04 几个星期了,今天突然无法连接 WiFi。我可以看到连接列表,但是无法连接——输入密码后,系统尝试连接但失败,并再次提示输入密码。这种情况发生了 3 次,之后什么也没发生,我无法连接。据我所知,我的路由器没有任何变化。有趣的是,即使我用我的 Android 手机连接热点,我也无法连接。我网络中的所有其他设备都没有连接问题。

我的 Ubuntu 16.04 与 Mac OSX 双启动,我可以毫无问题地连接到 WiFi。

这是有关我的无线适配器的一些附加信息。

$ sudo lshw -C network
  *-network

有谁能帮我解决这个问题?
