Acabei de receber meu laptop Asus K53S de um reparo (a tomada de energia CC foi substituída) e meu wireless não funciona.
O sinal Wi-Fi é extremamente baixo ou inexistente e não consigo me conectar com sucesso, mesmo se outros dispositivos estiverem conectados com bom sinal.
Rodando sudo lshw -C network
, obtenho:

Executando sudo iwlist scan
com dois strongs sinais de Wi-Fi ao alcance, muitas vezes recebo "nenhum resultado de verificação", mas quando obtenho uma resposta, aqui está um exemplo:

Eu também tentei inicializar o Ubuntu 16.04 a partir de um live CD, e eu tenho exatamente o mesmo comportamento.
Isso prova que há algo de errado com o hardware? Por favor sugira mais alguma informação que eu possa compartilhar.
