Соединенное проводное соединение, но никакой доступ в Интернет

У меня есть Ноутбук HP Compaq nx6310, и я недавно установил Ubuntu 13.04 на нем. Мне подключили Маршрутизатор TP-Link WR720N к другой системе, работающей на Windows 8 Pro. Проблема, я могу соединиться с маршрутизатором, но доступ в Интернет не доступен в моей системе Ubuntu, но хорошо работает с Windows. Помогите мне в этом отношении.
