Wi-Fi, не работающий в человечности 14.04 внезапно

Мой Wi-Fi не обнаруживает соединений Wi-Fi, хотя они присутствуют.

Как только я запускаю свою сеть системы, Разъединенное уведомление обнаруживается. Но это, оказывается, работает когда-то, и это тихо странный.

Также нет никакой опции включить Wi-Fi в опциях Wi-Fi как он, для, позволяют объединиться в сеть.

Другие люди также сообщили о подобных проблемах: Внезапно остановленный показ моего Wi-Fi в человечности 14.04 в списке в Dell Inspiron 5420?

Я работал, диагноз при Моем соединении беспроводной связи/Wi-Fi не работает. Какая информация необходима для диагностирования проблемы?
