Ubuntu 16.04下的HP 17-y020ca WiFi始终被禁用或“未就绪”
我最近购买了HP笔记本17-y020ca并安装了XUbuntu 16.04。 这款笔记本拥有Broadcom Corporation BCM43142无线网卡。
最初未检测到此无线网卡（但以太网卡工作正常），我按照以下说明操作：
是否可以在Ubuntu 16.04中使用Broadcom BCM43142 wifi？
现在看起来通常检测到卡，并且在XFCE的网络菜单中将“启用WiFi”作为活动（非灰色）选项给出。
当我点击“启用WiFi”时，此菜单通常会通过“启用WiFi”旁边的复选标记更改状态以指示它已启用。 但是，当发生这种情况时，菜单中会进一步发生以下两种情况之一。 要么说：
“Wi-Fi已停用”或“Wi-Fi未就绪”
我运行了wireless-info.bash脚本并包含在下面。
对于任何人都可以给出的任何建议，我将非常感激。 非常感谢您的考虑！
真诚的，纳撒尼尔奥斯古德
