我刚刚在 Dell Precision M6500 上安装了 Ubuntu 17.1（因此这台笔记本电脑是 2009-2010 年的旧款），同时还安装了 Windows 7。在 Windows 中，wifi 工作正常（并且 LED 亮起，就在键盘上方）。在 Ubuntu 中，没有 wifi，wifi 灯熄灭，如果我转到 Ubuntu 设置，wifi 页面会显示没有 wifi 适配器。如果我尝试 lspci 命令，我会得到 Broadcom 设备的以下信息：
dell-M6500:~$ lspci -nnk |grep -iA3 broadcom

如果我按照如何离线安装 Broadcom 无线驱动程序？，我得到了这个：

这台笔记本电脑不支持 UEFI 启动，因此没有可以关闭的安全启动选项（我也查看了 BIOS，但找不到任何与安全启动相关的内容）。BIOS 是最新的（A10）。
关于如何让 wifi 正常工作，您有什么想法吗？
答案1
Broadcom 驱动程序安装失败，因为多个软件包依赖项未安装，并且至少在一个情况下，依赖项的依赖项未安装！
你有两个选择。第一个是一分钟选项。向朋友或亲戚请求或借用以太网连接。如果需要，可以用六罐他们最喜欢的饮料贿赂他们。然后打开终端并执行：
sudo apt update
sudo apt install -f bcmwl-kernel-source
完毕！
第二种选择，通常是一周的选择，方法是：https://packages.ubuntu.com/选择巧，Ubuntu 17.10 的代号。找到缺少的软件包，在你的情况下是 linux-libc-dev、make、build-essential 和 dpkg-dev。一定要下载依赖项的依赖项。例如，如红点所示，制作依赖于 libc6。
您可以使用以下命令检查它是否已安装：
sudo dpkg -s libc6
在我的系统上，它已经安装好了，所以我看到：
Package: libc6
Status: install ok installed
请务必根据需要下载 32 位或 64 位版本。使用终端命令查找：
arch
如果返回 x86_64，那么您需要这些包的 64 位版本，也称为 amd64。
将所有这些数据传输到 USB 密钥或类似设备上，然后像之前一样进行安装：
sudo dpkg -i *.deb
如果仍有缺失的依赖项，请返回并重试。
我不太清楚你是如何在没有常用软件包 linux-libc-dev、make、build-essential 和 dpkg-dev 的情况下安装 Ubuntu 的，但这个过程应该可以纠正安装。

最终，chili555 发布的 2 条命令是必要的，但对我而言还不够。以下是我必须执行的操作：
第一次更新做了这样的事情：

Done bcmwl-kernel-source is already the newest version (6.30.223.271+bdcom-0ubuntu3). You might want to run 'apt --fix-broken install' to correct these.

Try 'apt --fix-broken install' with no packages (or specify a solution).所以我运行了修复程序。有趣的是，有关于 wl 的输出，我推测是针对无线的：

然后我注意到键盘上方的 wifi LED 亮了。LED 很可能是在步骤 4 之后亮起的，但也有可能是在步骤 1、2 甚至 5 之后亮起的。
