![Ubuntu 18.04 在 ThinkPad T440s 上未找到 Wi-Fi 适配器](https://linux22.com/image/1011095/Ubuntu%2018.04%20%E5%9C%A8%20ThinkPad%20T440s%20%E4%B8%8A%E6%9C%AA%E6%89%BE%E5%88%B0%20Wi-Fi%20%E9%80%82%E9%85%8D%E5%99%A8.png)
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

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
