Ubuntu 18.04 在 ThinkPad T440s 上找不到 Wi-Fi 适配器

  • 772

我是 Linux 新手，刚刚安装了 Ubuntu 18.04，第二个系统是 Windows 10，我的笔记本是 ThinkPad T440s。当我在 Ubuntu 上时，我无法访问 Wi-Fi，因为它显示没有 Wi-Fi 适配器。我做了一些研究，我认为我没有驱动程序或其他东西，但我无法在终端下载任何东西，因为我只使用 Wi-Fi，我没有连接互联网的电缆。我在终端中检查了我的网络控制器的名称是什么，它是 Intel Corporation Wireless 7260。

输出lshw -C network：

    因此，从 Ubuntu 安装所有数据包后，我编写了此命令并下载了所有驱动程序

    sudo modprobe iwlwifi && dmesg | grep iwl
