Meu sistema foi atualizado de 12 a 14.04 hoje.
Eu executei apt-get upgrade , que corrigiu a GUI quebrada
No entanto, minha conexão com fio falhou depois disso.
O Ubuntu continua tentando se conectar à Internet e falha com:
Disconnected - you are now offline" shows up continuously.
Aqui estão algumas informações para referência.
