Minha conexão sem fio continua caindo após cerca de 10 minutos. Parece acontecer quando estou mergulhada na máquina, mas pode ser apenas coincidência.
Algumas das coisas que tentei estão desligando o N no roteador e adicionando estes e estas sugestões para rc.local . Além disso, eu estava recebendo No probe response ... after 500ms, disconnecting anteriormente (como aqui ).
Eu também tentei instalar o driver mencionado aqui , mas a compilação falhou para mim.
Qualquer ajuda seria apreciada!
Aqui está a saída de wireless_script :
