Плохое Соединение с моим Intel Wireless-N Dual Band 7260 Adapter

Я запускаю Ubuntu 14.04 и могу только получить Интернет, работающий некоторое время. С нескольких моментов просмотра все еще подключен маршрутизатор, но я не получаю Интернет-соединения. Я понятия не имею, как зафиксировать это. Следует иметь в виду, что я плохо знаком с Ubuntu.
