Обновлен до Ubuntu 14.04 без беспроводной связи

Я только что обновил и потерял беспроводное соединение. Вот некоторая базовая информация, которая может быть полезна:

• Двухъядерный процессор Dell Inspiron i3-3217U @ 1,8 ГГц, 64-битный
• ID чипа: BCM43143
• PCI -ID: 14e4: 4365
• Используемый драйвер ядра: bcma-pci-bridge

Ниже результата команды sudo lshw -C network:
