Answer 1

A solução é bem simples. Conecte seu computador à internet através de um cabo ethernet. Se você não tiver um extra, poderá usar o cabo entre o roteador sem fio e o modem a cabo / DSL. Em seguida, abra o programa Drivers adicionais pesquisando-o no painel. Selecione seu driver na lista e clique em "Ativar". Forneça sua senha, relaxe, deixe-a instalar e, em seguida, reinicialize quando solicitado.
