После Wi-Fi отключения и перевключения, не может соединиться снова
Я отключил WiFi на своей машине Ubuntu 14.04 для проверения этого дважды некоторые файлы, в которых я нуждался, будет доступен в режиме офлайн позже. После перевключения WiFi я не мог снова соединиться со своей беспроводной сетью. Я попытался перезапустить, отключив/разрешив сети, rfkill блокируют/разблокируют Wi-Fi и пару других предложений, которые я нашел на форумах. Это происходит довольно часто. Каждый раз, когда я отключаю WiFi и затем повторно включаю его, я часто испытываю затруднения при повторном подключении. Я не смог приземлиться на ряд шагов, который последовательно работает. Насколько я могу сказать, это снова соединяется наугад каждый раз, когда это хорошо и готово.
Кто-либо знает непротиворечивое множество шагов, которые я могу сделать для повторного подключения, когда это происходит? Причиной всегда является то же, таким образом, я думал бы, что решением должно всегда быть то же, также.
Требуемый вывод
Обратите внимание, что в то время, когда я запустил скрипт, я не испытывал проблему. У меня было успешное и длительное соединение.
