16.04 LTS 中缺少 WiFi

  • 772

所以我最近在我的机器 Thinkpad X1 Carbon 4th gen 上安装了 ubuntu 16.04 LTS，当时我最终想要进行全新安装。我以前从来没有遇到过 wifi 问题，但是你瞧，全新安装 16.04 LTS 后，“启用 wifi”选项就消失了。

从 USB wifi 启动时工作正常，但在已安装的版本上它不会出于任何原因。使用时，sudo lshw -c network我收到*-network UNCLAIMED有关我的 Intel 8260 的消息。

我找到了一两个相对粗略的解决方法，但我不确定这是必要的，因为它在几个小时前就开始运作了？

sudo modprobe iwlwifi && dmesg | grep iwl返回：

    如果没有正确的固件，我们不太确定您是如何安装的。让我们修复它。使用临时有效的互联网连接，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，您的无线应该可以工作。
