Не может получить доступ ни в какие веб-сайты .wordpress.com

Несколько дней назад я взял широкополосное соединение. Я настроил кабельное соединение DSL от администратора сети и использование имени пользователя и пароля, который я мог отлично подключить к Интернету. Но я нашел, что не могу получить доступ ни в какие блоги .wordpress.com и некоторые другие веб-сайты. Это показывает просто загрузку, но веб-страница не появляется.

Я использую ubuntu 14.04 LTS.

Вот вывод ifconfig
