Wifi no funciona en ubuntu fresco 16.04

En primer lugar, lo siento si este hilo está duplicado con otro, pero no encontré una solución para el problema.

Así que compré una nueva computadora portátil (Lenovo Y520) y configuré el arranque dual Win10 con Ubuntu 16.04 y la conexión inalámbrica no funciona para la ubuntu (LAN funciona).

Cosas que he probado y no funcionaron.

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

Correr en una terminal

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

y reiniciar Esto debería desbloquear tu wifi.
