Подключение к Wi-Fi на XUbuntu?

Я немного новичок в Ubuntu и пытаюсь следовать документам XUbuntu, но у меня возникли некоторые проблемы.

Сетевой менеджер не имел никакой возможности подключиться к Wi-Fi, поэтому я предположил, что это потому, что драйвер не был установлен.

Первой проблемой, с которой я столкнулся, был ввод sudo lshw -C network, и я не видел CLAIMED/ DISABLED/ ENABLED/ UNCLAIMED.

Второй пытался установить драйвер для моего компьютера. Я проверил свой диспетчер устройств в Windows, увидел, что это сетевой адаптер Broadcom 802.11n, и загрузил драйвер локальной сети от Lenovo. Затем я попытался установить этот драйвер с помощью беспроводных драйверов Windows, но он не работал. Сказал мне, что он не узнал водителя.

Не уверен, что еще попробовать.
