Как установить беспроводную карту Broadcom / STA (BCM43XX)

Недавно я установил Ubuntu 12.10 на ноутбук друга, но у меня возникли проблемы с его работой. его беспроводной маршрутизатор. Я могу подключиться к Интернету и нормально использовать его с подключением Ethernet, но многие беспроводные подключения, которые я пытался настроить, отображают «последнее использованное» как «никогда ...» Я не уверен, какая информация / изображения будут необходимо либо перейти на рабочую версию, либо получить для подключения текущую версию.
