Я не уверен, что из-за аппаратного сбоя требуется обратиться в сервисный центр (я очень надеюсь, что это не так), иногда мой ноутбук не получает доступ к Wi-Fi-устройству. Устройство продолжает прятаться в течение определенных часов и внезапно появляется.

Что будет лучшим выбором, если я попытаюсь связаться с устройством?

Вот несколько журналов. Первые три команды, которые я знаю, взяты, когда устройство Wi-Fi находится в пределах досягаемости. Вторые три взяты, когда устройство скрыто.

Без проблем
