问题描述
我已经安装了Ubuntu和Windows 8.1。但是无法在Ubuntu中运行(也许驱动程序不存在)，这在Windows中运行良好。因为我的笔记本电脑没有以太网端口，所以我无法连接以太网。那么有什么方法可以让我在ubuntu上连接到互联网吗？编辑：终端命令lspci -knn | grep Net -A2的输出：
vikram@vikram-Inspiron-11-3148:~$ lspci -knn | grep Net -A2

我做了Pilot6建议的。这是输出：
vikram@vikram-Inspiron-11-3148:~$ sudo dpkg -i *.deb

最佳解决思路
您需要安装无线驱动程序。
插入您的Ubuntu安装盘或闪存驱动器，并将这些文件从安装盘复制到您的主目录：
pool/main/d/dkms/dkms_XXXXX.deb
pool/restricted/b/bcmwl/bcmwl-kernel-source_XXXXX.deb
然后在终端中运行以下命令：
sudo dpkg -i *.deb
如果您有UEFI BIOS，则需要禁用安全启动以加载驱动程序。
18.04更新：
该解决方案将无法在18.04上运行，因为默认情况下不安装build-essential及其依赖项。 dpkg命令将抱怨未安装依赖项。
您可以在安装介质上手动查找所需的软件包(按字母顺序排序的”pool”目录)，并以与dkms软件包相同的方式安装它们。我希望那里没有什么遗漏。
