Больше не может соединяться с некоторым WiFis

Моя проблема, который я не могу подключить к некоторому WiFis, в то время как другие все еще работают. Все хорошо работало неделю назад. Мобильная точка доступа, созданная моим телефоном, все еще хорошо работает.

Эта проблема более распространена, так как я часто отправляю свой ноутбук для сна вместо закрытия. Я проверил Беспроводные сети вопроса, не работающие после резюме в Ubuntu 14.04, но это не помогло.

Я был бы благодарен за любую справку с этим, включая указатели, который регистрируется, и т.д. мог обеспечить больше понимания.

Тем не менее жаль о неопределенном заголовке, не стесняйтесь редактировать для разъяснения.

Что точно происходит

1. Я (ре) запускаю.
2. Значок администратора сети показывает связанный WiFi.
3. В быстрой последовательности следующие уведомления показывают:
   • мой Wi-Fi: Соединение мой деактивированный Wi-Fi
   • Беспроводной интерфейс (wlan0): Никакие секреты не были обеспечены
4. Отбрасывания соединения, администратор сети показывает "поиск", затем "соединяющийся" значок.
5. Происходят несколько повторений (~3). Каждый показывает следующие два уведомления:
   • мой Wi-Fi: Соединение мой деактивированный Wi-Fi
   • Беспроводной интерфейс (wlan0): конфигурация IP была недоступна.
6. После повторений администратор сети показывает вопросительный знак и сдается.
