Actualmente tengo instalado Ubuntu 14.04 LTS en mi computadora portátil. El WiFi se conecta sin ningún problema, pero cuando intento acceder a Internet se vuelve imposible. Funciona bien con una conexión de palanca USB inalámbrica. El módulo inalámbrico interno no funciona correctamente
¿Qué puedo hacer para arreglar esto? Mi portátil es Toshiba Satellite A500.
