16.04 LTS 缺少 WiFi

因此，我最近在我的 Thinkpad X1 Carbon 4th gen 机器上安装了 ubuntu 16.04 LTS，但最后我还是想进行全新安装。我之前从未遇到过 wifi 问题，但没想到在全新安装 16.04 LTS 后，“启用 wifi”选项就消失了。

从 USB 启动时，WiFi 工作正常，但安装的版本不知为何却不行。使用时，sudo lshw -c network我收到了*-network UNCLAIMEDIntel 8260 的消息。

我找到了一两个相对粗略的解决方法，但我不确定这是否有必要，因为它在几个小时前才开始运行？

sudo modprobe iwlwifi && dmesg | grep iwl返回：

我们不太确定您是如何在没有正确固件的情况下安装的。让我们来修复它。在临时可用的互联网连接下，打开终端并执行以下操作：

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.15_all.deb
sudo dpkg -i linux*.deb

重新启动后你的无线网络就能够正常工作了。
