首先我要说的是，在发帖之前我尝试过不同的方法。安装 Ubuntu 16.04 LTS 后，wifi 完全被禁用。它显示 Wi-fi 已禁用。在尝试了这个问题中的所有解决方案后如何使 RT3290 无线网卡工作？它开始显示 Wi-fi 网络，但没有可用的连接。然后我尝试了Ubuntu 16.04 中不显示 Wifi 网络，但当时根本没有 Wi-fi 网络。然后我做了`
sudo ifconfig rename3 up *(rename3 is the logical name of my wireless interface)*
sudo systemctl restart network-manager
此后它回到之前的阶段但仍然没有显示任何可用的 wifi 连接。
sudo lshw -C 网络

我刚刚从 Windows 切换到 Linux，有点迷茫，两天来我一直在尝试让它工作。请提供一些帮助，这真的很棒，我真的想继续使用 Linux。
在尝试了 ubuntu 16.04 后，我安装了 14.04。全新安装后
rfkill 列出全部

然后我发现另一个问题已经解决了Ralink rt3290 wifi 驱动程序在 Ubuntu 14.04 中不起作用并尝试了解决方案，然后情况发生了变化。
rfkill 列出全部什么都没显示，sudo lshw -C 网络给出了以下输出，其中*-network DISABLED无线接口不再存在。
