Atualmente, não consigo me conectar à Internet no meu Ubuntu 14.04 recém-atualizado. O Network Manager é capaz de identificar redes sem fio e pode detectar quando estou conectado a uma conexão Ethernet, mas sempre parece ter tempo limite ao tentar se conectar. Eu tentei isso tanto no trabalho como em casa e obter os mesmos resultados.
