Linux получил IP-адрес от DHCP, но до сих пор не может подключиться к WPA2 WIFI

4

Здесь у меня проблема.

У меня есть беспроводной маршрутизатор, который является Buffalo WCR-HP-GN, и я устанавливаю WIFI, который использует аутентификацию WPA2-PSK и кодовую фразу, зашифрованную TKIP. Пароль представляет собой 9-буквенные номера.

У моей жены есть macbook, и она может подключаться к Wi-Fi. Но мой lenovo x200 с Ubuntu 12.04 LTS не может подключиться к Wi-Fi. Я проверил настройки и IP, все в порядке. Я могу получить IP через dhclient , но когда я пытаюсь использовать ping шлюза, он не работает. Если я попытаюсь подключить его с помощью проводного Ethernet-кабеля, и все в порядке, я могу ping шлюза.

Может ли кто-нибудь сказать мне, что случилось и как его решить? Спасибо!

Вот код dmesg , когда я подключаюсь к Wi-Fi.

Я пытаюсь выяснить проблему, и я обнаружил, что на одном канале есть много сигналов. Я меняю канал, я могу выполнить ping IP-адрес маршрутизатора. Я отредактирую этот ответ, пока я получу подробный журнал:)

Попробуйте подключиться по беспроводной сети, а затем с помощью другого устройства просмотрите страницу маршрутизатора и посмотрите, содержит ли он ваш хост как подключенный.

Кроме того, я вижу это в ваших журналах:

192.168.11.3

Это IP-адрес, назначенный вашему компьютеру? Если это так, попробуйте назначить статический IP-адрес с вашего маршрутизатора на MAC-адрес этого компьютера или установить статический IP-адрес в Ubuntu . Измените его на что-то внутри домена маршрутизатора, например

192.168.11.13

(предполагая, конечно, что этот IP еще не принят)
