У меня нет беспроводной связи

У меня нет беспроводного соединения на рабочем столе. Когда я пытаюсь подключиться, используя значок беспроводной сети на панели, он говорит: Ethernet Network (Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller disconnected.

Как я могу это исправить, чтобы мой рабочий стол подключался к беспроводному маршрутизатору без использования кабеля Ethernet?
