Este es un problema en 13.04 y es un problema con el wifi. Ubuntu nunca se conectará a la red. Todos mis otros dispositivos funcionan bien.
La computadora detecta la red y abre el diálogo de contraseña wifi. Ingreso la contraseña correcta, hago clic en Aceptar e intenta conectarse durante unos segundos y luego solicita la contraseña nuevamente. Estoy usando un nuevo adaptador USB D-Link Wireless N 150 Pico que funciona bien en Windows para conectarse a la misma red.
Busqué en Google por unas horas y no encontré una respuesta, ¿tal vez alguien aquí podría ayudar?

Puede intentar desactivar el ahorro de energía inalámbrico que tiende a desconectar la tarjeta demasiado pronto:
Editar: algunas sugerencias más ...
De la salida que envió podría ser que el ipv6 no se puede conectar
Edite las conexiones> elija su red y luego haga clic en editar> pestaña IPV6> establezca el método para "ignorar"
He visto otros hilos con personas que tienen problemas con los certificados: Autenticación en red inalámbrica
y comentar la línea (poner un # delante de) system-ca-cert = true
¿Podría ser un problema de firmware para su adaptador USB? Puede intentar conectarse a través del cable de Ethernet y realizar una actualización a través del actualizador de software.
Lo último que le viene a la mente, simplemente elimine la conexión actual y comience de nuevo ...
Háganos saber cómo te fue

Como puedo ver, dhclient no puede recuperar la IP del enrutador. Al menos IPv6. Por lo tanto, intente configurar IPv6 para "ignorar" y / o habilitar / deshabilitar el uso de IPv6 / IPv4. Todo esto no me ayudó (tengo el mismo registro). Configuré IPv4 manualmente. Como primero configuro IP aleatorio y solo me conecto al enrutador. Aquí no tengo Internet pero estoy conectado al enrutador. Luego busqué la red para encontrar la IP del enrutador: nmap 192.168.0.0/23 y luego configuré la IP del enrutador como puerta de enlace.
Esta no es una solución para todas las situaciones, pero esta noche me ayudó a conectarme al wifi gratuito del hotel. También tuve que configurar DNS. Utilicé google public dns pero puedes configurar cualquier otro.
