Адаптер Wi-Fi не найден (Ubuntu 18.04, Acer Predator Helios 300) Решение?

Question

Я не могу подключиться к беспроводному соединению через Ubuntu. Я попытался запустить sudo apt-get install --reinstall bcmwl-kernel-source, а затем перезагрузил свой ноутбук, он не работал.

Я также сослался на инструкции в этом видео . Все еще не работает.
