Linux получил IP от DHCP, но все еще не может соединиться с WI-FI WPA2

Здесь я получил проблему.

У меня есть Беспроводной маршрутизатор, который является Buffalo WCR-HP-GN, и установка I WI-FI, которые используют аутентификацию WPA2-PSK и пароль, зашифрованный TKIP. Пароль является числами с 9 буквами.

У моей жены есть MacBook, и он может соединиться с Wi-Fi. Но моя lenovo x200 с Ubuntu 12.04 LTS не может соединиться с Wi-Fi. Я проверил установку и IP, все прекрасно. Я могу передать IP dhclient, но когда я пытаюсь ping шлюз, это не работает. Если я пытаюсь соединить его с проводным кабелем Ethernet, и все прекрасно, я могу ping шлюз.

Кто-либо может сказать мне, что произошло и как решить его? Спасибо!!

Вот dmesg зарегистрируйтесь, в то время как я соединяюсь с Wi-Fi.
