Ambas as ligações à Internet com e sem fios diminuem. Quando tento acessar uma página da Web com o Firefox, obtenho a mensagem não conectada à internet . Quando clico várias vezes em tente novamente , ele funciona de repente por um tempo. Em um sistema com Windows, a velocidade é boa com o mesmo cabo.
Propriedades da conexão com a Internet:
method: automatic (DCHP)
MTU: automatic.
Devo (posso) editar a conexão com a internet e definir propriedades manualmente para resolver o problema?
Eu tentei alguns comandos para fornecer algumas informações.
