我对 Ubuntu 还不太熟悉，一直在尝试遵循 XUbuntu 文档，但遇到了一些麻烦。
网络管理器没有任何连接 Wifi 的选项，所以我认为这是因为没有安装驱动程序。
我遇到的第一个问题是输入 sudo lshw -C network 但看不到 CLAIMED/ DISABLED/ ENABLED/ UNCLAIMED。
第二个是尝试安装电脑驱动程序。我在 Windows 上检查了设备管理器，发现它是 Broadcom 802.11n 网络适配器，并从联想下载了 LAN 驱动程序。然后我尝试使用 Windows 无线驱动程序安装该驱动程序，但没有成功。告诉我它无法识别驱动程序。
不确定还能尝试什么。

答案1
首先，删除您ndiswrapper用来尝试使用 Windows 驱动程序的...
在terminal...
sudo apt-get purge ndiswrapper-dkms
note: you may have to change "ndiswrapper-dkms" to something
else, depending on what you originally installed
现在我们安装博通驱动程序...
sudo apt-get update
sudo apt-get install dkms broadcom-sta-dkms
reboot
secure boot在重新启动期间，在 BIOS 中禁用。
完毕！

您可以在输出中看到，没有列出适用于您的 Broadcom 无线芯片 (43142) 的驱动程序。不幸的是，Broadcom 是一家非常受欢迎的制造商，但其对 Linux 的支持也很差，这完全是他们的错。通过研究您的芯片组，您唯一的选择是尝试使用专有的 Broadcom 驱动程序，即 STA/WL。这应该可以帮助您安装它们。
