Где кроется причина проблемы
Данная ошибка появляется при некорректной работе сетевой карты. Процессор не “видит” последнюю и не способен к ней “обратиться”. Как видно на первой картинке, название ошибки дополнено ее описанием If Deep Sleep Mode enabled Please Plug the Cable. Это означает невозможность запуска сетевой карты из-за того, что она не выходит из спящего режима вместе с другими составляющими компьютера. Что при этом происходит?
- Отключается соединение с сетью.
- Мы не видим в диспетчере устройств установленное на компьютере оборудование, обеспечивающее подключение к интернету.
Конечно, сетевой адаптер мог совсем выйти из строя, и теперь необходимо покупать новый. Но перед этим крайним шагом нужно попытаться исправить ошибку всеми известными способами.
Способы исправления ошибки сетевой карты
Избавиться от ошибки «The Realtek Network Controller was not found» можно установив обновление или переустановив драйвера, отключив питание сетевой карты, изменив свойства контроллер, и рядом других способов. Ознакомимся с ними и попробуем их в деле.
Обновляем или переустанавливаем драйверы
Попробуем обновить либо переустановить драйверы.
- Заходим в “Диспетчер устройств” (в Windows 10 выбираем его после клика ПКМ по кнопке “Пуск”).
- Раскрываем строчку “Сетевые адаптеры” и нажимаем ПКМ на Realtek PCIe GBE Family Controller.
- Обновляем драйверы, выбирая автоматический поиск.
- Если драйверы для сетевого адаптера актуальны, то система выдаст сообщение о том, что они не нуждаются в обновлении. Тогда мы снова нажимаем ПКМ на название сетевой карты и удаляем инсталлированные драйверы.
- Затем скачиваем нужный софт с официального сайта и устанавливаем на свой ПК.
Если это не помогает исправить ошибку, пробуем другой вариант.
Изымаем сетевую карту и отключаем питание
Второй способ предполагает изъятие сетевого адаптера из корпуса и возврат его на место, после чего контроллер должен выйти из режима “глубокого сна”. Сделать это нужно правильно, соблюдая определенный порядок действий.
- Полностью отключаем компьютер от сети.
- Очень (!) аккуратно извлекаем планки оперативной памяти из слотов материнской платы, где они установлены.
- Оставляем все устройства в покое примерно на полчаса. Чем дольше, тем лучше, так как подобный прием должен прервать режим глубокого сна сетевого контроллера.
- Устанавливаем на место планки оперативной памяти.
- Запускаем Windows и проверяем, подключился ли компьютер к сети.
Если и это не помогает решить проблему, то извлекаем батарею из ноутбука или отключаем стационарный ПК от сети на срок до 12 часов и по истечении этого времени вновь запускаем устройство.
Пробуем “разбудить” сетевую карту при помощи внешнего накопителя
Завершаем работу компьютера, подсоединяем к нему внешний жесткий или USB-накопитель и запускаем систему. Вместе с попыткой компьютера установить новое устройство должен “проснуться” и сетевой контроллер. Не помогло – идем дальше.
Изменяем свойства сетевого контроллера
- Раскрываем в диспетчере задач сетевые адаптеры и делаем двойной щелчок ЛКМ по Realtek PCIe GBE Family Controller.
- Появляется окно “Свойства”, и мы переходим во вкладку “Дополнительно”.
- Здесь выбираем “Скорость и Дуплекс”.
В блоке “Значение” нажимаем на “Автосогласование” (Auto Negotiation), выбираем из выпадающего списка скорость 10 Мбит/с с дуплексом (10 Mbps Full Duplex) и подтверждаем действие.
После этого перезагружаем компьютер и проверяем, удалось ли нам “разбудить” сетевой адаптер.
Проверяем питание контроллера в BIOS
Проверим в BIOS, включено ли питание сетевого адаптера.
- Запускаем систему, входим в BIOS и ищем настройки Onboard Lan (или другую, в названии которой есть Lan) или Integrated NIC.
- В этом пункте должно быть указано значение Enabled “Включено”.
- Если указано обратное, включаем питание, перезагружаем компьютер и снова проверяем работу сетевой карты.
Как предотвратить проблему
- Мало исправить ошибку, проявляющуюся в данный момент. Нужно еще сделать так, чтобы проблема не возникала в будущем.
- Открываем свойства сетевого адаптера в диспетчере устройств и переходим во вкладку “Управление электропитанием”.
- Убираем галочку в квадратике напротив строки “Разрешить отключение этого устройства для экономии энергии”.
- Подтверждаем действие и перезагружаем ПК.
Один из этих способов наверняка поможет избавиться от ошибки The Realtek Network Controller was not found, если, конечно, сетевая карта полностью работоспособна.
