我的 Wifi 卡无法被识别。我想这可能是因为硬件比较新（这是一台新的戴尔 Precision 笔记本电脑）。一直在尝试弄清楚如何反向移植新驱动程序，但似乎已经启用了，所以也许我必须转到较新的内核。我已将 wifi 脚本的输出粘贴在下面。任何建议都非常感谢！

答案1
在 Ubuntu 16.04 中包含的内核版本中，您的确切设备 8086:24fd 和子系统 0050 尚未被覆盖。它在 Ubuntu 17.04 中被覆盖；从我的机器来看：
$ modinfo iwlwifi | grep 0050
alias: pci:v00008086d000024FDsv*sd00000050bc*sc*i*
您当然可以重新安装并使用 17.04 而不是 16.04。您也可以下载并安装 4.10-xx 内核和所需的固件。如果您更愿意选择后者，那么我假设您的安装是 64 位；确认：
arch
如果终端返回 x86_64，则说明您的安装是 64 位。将文件下载到您的桌面：
http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.164_all.deb
从终端安装它们：
cd ~/Desktop
sudo dpkg -i *.deb
重新启动并告诉我们您的无线是否正常工作。
答案2
在存储库之外安装内核不是一个好主意，因为您会错过安全更新。您应该安装Ubuntu HWE反而。
sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04
这将升级您的内核和 xorg 堆栈。此时，它会将您升级到 Ubuntu 17.10（内核 4.13）的内核。
