我在我的笔记本电脑上全新安装了 Ubuntu 16.04.3，我的笔记本电脑也运行着 Windows 10。安装成功，在此过程中，我可以毫无问题地连接到我的 wifi 网络（使用 Windows 时我仍然可以这样做） - 但现在当我尝试选择一个网络时，根本看不到任何网络。我可以使用有线连接。
使用sudo lshw -C network，我得到：

我以为这可能是缺少驱动程序的问题，因为驱动程序无人认领，所以我从这里至/lib/firmware，但仍然没有结果。
我尝试了其他几种解决方案，例如检查软件更新和附加驱动程序，但很多都是针对以前的版本，所以我发现它们没有做出任何改变。内核版本是否有4.13.0-1015-oem帮助。

我们想知道为什么没有安装相应的固件包。请尝试：
sudo apt update
sudo apt install --reinstall linux-firmware
查看：
ls /lib/firmware | grep 8000
我们希望你看到：
iwlwifi-8000C-13.ucode
iwlwifi-8000C-16.ucode
iwlwifi-8000C-21.ucode
iwlwifi-8000C-22.ucode
iwlwifi-8000C-23.ucode
iwlwifi-8000C-24.ucode
iwlwifi-8000C-27.ucode
iwlwifi-8000C-31.ucode
如果是这样，请重新启动，然后你的无线就应该可以正常工作了。
