Установлен Xubuntu, но в NetworkManager нет опции WiFi [дубликат]

Только что успешно установил Xubuntu 16.04 (ну, почти успешно), так как теперь у меня, кажется, нет возможности включить какой-либо WiFi - такой опции просто нет в NetworkManager.

Совершенно новый для Llinux / Xubuntu, но рад использовать терминал, если посоветуют.

Здесь есть множество ответов по этому вопросу, я не уверен, какой из них применим к моей конкретной проблеме.

Я подключаюсь к Интернету через точку доступа iPhone - никаких проблем с подключением через нее к моему MacBookPro, iPad или кому-либо еще, кто посещает меня и хочет подключиться, всегда может это сделать. Однако на моем Macbook (да, Macbook !!), на котором я только что установил Xubuntu с двойной загрузкой, я не могу видеть или подключаться к какой-либо точке WiFi.

Кто-нибудь может посоветовать, что мне делать дальше? Спасибо
