Thinkpad T460 Wifi 无法使用

我刚刚对我的 Windows 机器进行了分区，并在分区上安装了全新的 Ubuntu 16.04，并进行了双启动。

不幸的是，WiFi 似乎无法使用 - 尽管我在家里的 WiFi 覆盖范围内，但看不到任何网络。此外，我无法访问有线连接。

我完全是菜鸟，但我正在尽我所能。在谷歌上搜索后，我发现此链接为无线适配器提供 Linux 支持，我想我可能需要安装额外的驱动程序？所以我从那个链接下载了驱动程序，他们说我只需输入/lib/firmware，然后我就开始做了……

这样做dmesg，我发现有一堆丑陋的错误：

我想象UNCLAIMED这意味着与无线设备通信出了问题？

正在做lsusb：

如果还有其他我可以尝试的方法，请在评论中告诉我！（每次我想尝试某件事时，我都需要重新启动进入 Ubuntu，并将文本写入闪存驱动器……）

答案1

请将此包下载到闪存驱动器上：http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.3_all.deb重启 Ubuntu 并将软件包拖放到桌面。然后打开终端并执行：

cd ~/Desktop
sudo dpkg  -i linux-firmware*.deb
sudo modprobe -r iwlwifi && sudo modprobe iwlwifi

你的无线网络现在能用吗？可能需要重启。

答案2

为了在 ubuntu 和 kali linux 上解决此问题，请运行以下命令安装 firmware-iwlwifi：

  1. sudo apt 安装固件-iwlwifi
  2. sudo 立即重启
