Сеть Wi-Fi не работает

Я просто обновил к Ubuntu 16.04 от 14,04. Я не проверял свое соединение WiFi ранее, но теперь я хочу использовать WiFi. Но, когда я пытаюсь использовать свой WiFi, он не обнаруживается в списке, и я не могу использовать его.

Я не уверен, что должно быть сделано.

После этого я изменился на устройство BCM4312 от обновления программного обеспечения и перезагружаю систему. Устройство использует альтернативный драйвер.

Тем не менее это не работает.
