Ubuntu 18.04 在 ThinkPad T440s 上未找到 Wi-Fi 适配器

我是 Linux 新手，刚刚安装了 Ubuntu 18.04，第二个系统是 Windows 10，我的笔记本电脑是 ThinkPad T440s。当我使用 Ubuntu 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，但我无法在终端中下载任何东西，因为我只使用 Wi-Fi，没有有线电缆连接互联网。我在终端上检查了我的网络控制器的名称，它是英特尔公司无线 7260。

输出lshw -C network：

我能做些什么 ？

因此，在从 Ubuntu 安装所有数据包后，我输入了这个命令，所有驱动程序都下载了

sudo modprobe iwlwifi && dmesg | grep iwl
