Wifi无法在新的ubuntu 16.04上运行
首先，我很抱歉，如果这个post与另一个重复，但我没有找到问题的解决方案。
所以我买了新的笔记本电脑（联想Y520）并设置双启动Win10与Ubuntu 16.04和无线无法工作的ubuntu（局域网工程）。

我运行了一些在另一个线程中找到的命令。

我测试过的东西并没有奏效。
* sudo rfkill unblock wifi * Additional Drivers -> Not showing wifi driver * restart network-manager service * http://askubuntu.com/a/859263
在终端中运行
sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"
并重新启动。 这应取消阻止您的Wi-Fi。
