Как включить WIFI на новом ноутбуке Ubuntu-Dell

Я только что купил новый ноутбук Dell и установил на него Ubuntu 16.04.4:

Когда я вхожу, я вижу это:

Ubuntu 16.04.4 LTS  Linux d79 4.4.0-127-generic #153-Ubuntu SMP Sat May 19 10:58:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux 

Wi-Fi не работает.

Я вижу здесь подсказку:

И я вижу здесь подсказку:

Я приветствовал бы любые идеи о том, как заставить WIFI работать на моем Ubuntu-Dell-Laptop.
