Проблема с подключением проводного интернета по MTNL Triband

Я являюсь пользователем Ubuntu из Мумбаи, Индия, и подписан на услугу широкополосной связи MTNL. У меня установлена ​​система двойной загрузки с Windows 7 и Ubuntu 12.04. Я получаю хорошее подключение к Интернету при работе в Windows 7, но в Ubuntu, хотя в меню отображается стрелка «вверх и вниз», обозначающая работающее соединение Ethernet, я не могу получить доступ к любому из веб-сайтов или выполнить какие-либо обновления Ubuntu с помощью терминал. В Windows подключение происходит автоматически, не требуя ввода имени пользователя или пароля. Основываясь на результатах поиска, который я сделал здесь, я нашел несколько команд, вывод которых помогает выявить проблему. Я публикую выходные данные трех из них в следующих строках: -
