Este problema está relacionado com a eficiência do driver do Linux. Se você tiver outro sistema operacional (como o windows 7,8 ..) efetue login no sistema operacional e ative o comutador wifi usando fn + F6 . Depois de habilitar o adaptador wifi no Windows, reinicie o sistema e faça o login no Ubuntu. Então você pode usar a funcionalidade wifi.
Felicidades Ubuntu geek
