Больше не может подключаться к некоторому WiFis
Моя проблема в том, что я не могу подключиться к некоторым WiFis, в то время как другие все еще работают. Все прошло отлично неделю назад. Мобильная точка доступа, созданная моим телефоном, все еще работает нормально.
Эта проблема более распространена, поскольку я часто отправляю свой ноутбук в режим сна, а не выключая его. Я проверил вопрос о том, что беспроводная сеть не работает после возобновления работы в Ubuntu 14.04, но это не помогло.
Буду благодарен за любую помощь в этом, включая указатели, журналы и т. Д. Могут обеспечить более глубокое понимание. [ ! d3]

Что именно происходит
I (re) start. Значок сетевого менеджера показывает подключенный WiFi. В быстрой последовательности отображаются следующие уведомления: my wifi: подключение моего Wi-Fi деактивированного беспроводного интерфейса (wlan0): никаких секретов не было. Соединение падает, сетевой диспетчер показывает «поиск», а затем значок «соединение». Проводятся несколько попыток (~ 3). Каждый из них показывает следующие два уведомления: мой Wi-Fi: подключение моего Wi-Fi деактивированного беспроводного интерфейса (wlan0): конфигурация IP недоступна. После повторных попыток сетевой менеджер показывает вопросительный знак и отказывается.Аппаратное обеспечение:
