Wi-Fi на Lenovo S20-30 не работает

Я совершенно новичок в Linux / Ubuntu и просто установил систему сегодня на моем Lenovo S20-30. Большинство вещей, похоже, работают, но я не могу получить беспроводное сетевое соединение. На данный момент я использую проводной Ethernet. Я попытался выяснить, что делать, и насколько я могу судить, что драйвер загружен - найден с sudo lshw -C network - но не загружен, если я правильно интерпретирую вывод modls.

Я запускал скрипт, предоставленный сообществом, и это результат:
