Broadcom STA беспроводной драйвер [дубликат]

При попытке активировать беспроводной драйвер, я получаю, что он не может быть активирован. Написано, что нужно проверить журналы. Я полный новичок в ubuntu и вообще пытаюсь узнать больше о компьютерах по ходу дела. Вот журнал. Любая помощь будет чрезвычайно признательна. Мое соединение ethernet работает нормально, если это имеет какое-то значение.

rfkill list all

Ничего не выдает. Возможно, проблема в чем-то здесь? Он не принимает доступные соединения. У меня есть кнопка жесткой блокировки, которая, как я считаю, не является проблемой на моем ноутбуке, и я проверил в настройках загрузки, чтобы убедиться, что беспроводные соединения включены.
