Wi-Fi не работает на свежем Ubuntu 16.04

Прежде всего, извините, если этот поток дублируется другим, но я не нашел решения для этой проблемы.

Поэтому я купил новый ноутбук (Lenovo Y520) и настроил двойную загрузку Win10 с Ubuntu 16.04, а беспроводная связь не работает для Ubuntu (LAN работает).

ifconfig

Я запустил несколько команд, которые нашли в других темах

sudo lshw -class network

Вещи, которые я проверял и не работал.

* sudo rfkill unblock wifi
* Additional Drivers -> Not showing wifi driver
* restart network-manager service
* http://askubuntu.com/a/859263

Запустить в терминале

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"

и перезагрузите компьютер. Это должно разблокировать ваш Wi-Fi.
