无法识别我的Wifi卡。我认为可能是因为硬件相对较新（这是一台新的Dell Precision笔记本电脑）。一直在尝试找出如何向后移植新驱动程序的方法，但是似乎已经启用了它，所以也许我不得不转向较新的内核。我已经粘贴了wifi脚本的输出下面。任何建议，不胜感激！

在Ubuntu 16.04中包含的内核版本中，尚未涵盖您的确切设备8086：24fd和子系统0050。在Ubuntu 17.04中有介绍。从我的机器上：
$ 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。您还可以下载并安装4.10-xx内核和所需的固件。如果您愿意选择后者，那么我认为您的安装是64位的；确认：
arch
如果终端返回x86_64，则您的终端是64位安装。将文件下载到桌面：
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设备是否正常工作。
