Quando o Ubuntu é iniciado, inicialmente ele mostra as conexões wi-fi próximas e tenta se conectar sem sucesso. Enquanto ele tenta, parece que o alcance que ele vê nas conexões Wi-Fi fica mais curto até que ele não veja nada e não consiga se conectar. Quando clico no ícone do Wi-Fi, ele diz "dispositivo não está pronto" abaixo de "Wi-Fi".
Quando executo sudo service NetworkManager status , ele retorna erros dizendo que tentou 5 vezes sem sucesso: "a interface do suplicante continua falhando, desistindo".

Eu vi alguns posts que acredito não serem totalmente iguais aos meus, então não sei como proceder.
