在笔记本电脑上安装了 Windows 和 Lubuntu 后，我发现我的无线网络无法使用（有线网络可以）。在 Google 上搜索了几个小时并尝试了许多其他方法后，我仍然无法解决问题。
说实话，我对 Linux 还算是个新手，但我认为这些信息会很有用：

如果有任何其他有用的信息，我会非常乐意提供。
编辑：
我忘了提了，但是无线连接在我双启动的 Windows 上确实有效。
可能重复： 安装 Broadcom 无线驱动程序 我已经尝试了这篇文章建议的步骤。首先，我安装了“bcmwl-kernel-source”包。重新启动后，我安装的另一个程序“WiFi Radar”中没有显示任何无线连接。在答案的后面，建议也尝试“firmware-b43-installer”。同样的事情发生了。上面的无线故障排除脚本的输出是在此步骤之后生成的。
Ubuntu 16.04 - 仅连接以太网，无 wifi 选项 我检查了安全启动是否已打开，但未打开。运行“sudo modprobe wl”时出现以下错误：在目录 /lib/modules/4.4.0-21-generic 中未找到模块 wl。
