Bom dia pessoal!Eu estou com um probleminha bem chato e gostaria de saber se alguém poderia me ajudar a resolver.
Eu comprei um notebook Dell Inspiron 15 - Série 5000 que chegou esta semana e veio com o Ubuntu. Entretanto, como utilizo o Mint, formatei a máquina e fiz a instalação da versão 17.3 (Rosa). Tudo correu perfeitamente e está tudo funcionando corretamente exceto pela Wi-Fi. O sistema simplesmente não reconhece a placa e tampouco consigo ver as redes disponíveis. Seguem algumas saídas que obtive pelo terminal:

$ rfkill list all
0: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
Somente o dispositivo de bluetooth está sendo reconhecido.
Sequer aparece o phy0: Wireless LAN.
Logo, o problema não é de soft block.

Eu instalei o último kernel disponível (4.4.0-22) imaginando que as configurações de firmware poderiam estar disponíveis. No entanto não adiantou. Busquei por dicas em diversos sites e fóruns, mas nenhuma sanou o problema até aqui.
Se alguém souber como eu posso solucionar este problema, ficaria agradecido se pudesse compartilhar. Caso necessitem de mais informações para melhor entendimento do problema, me comuniquem, por gentileza.
Abraços e um bom fim de semana a todos!
