![全新安装的 Ubuntu - 未发现任何 Wifi 网络](https://linux22.com/image/1005523/%E5%85%A8%E6%96%B0%E5%AE%89%E8%A3%85%E7%9A%84%20Ubuntu%20-%20%E6%9C%AA%E5%8F%91%E7%8E%B0%E4%BB%BB%E4%BD%95%20Wifi%20%E7%BD%91%E7%BB%9C.png)
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。
