Bom dia galera, instalei recentemente o Linux Mint Cinnamon 19.1 no meu PC, mas ele não está mostrando as redes wi-fi disponíveis. Já tentei algumas soluções que vi por aqui, como desabilitar o Secure Boot, tentar rodar o mint em outro kernel, alguns updates na rede, mas nenhum funcionou. No momento estou usando a rede internet via USB Tethering do meu celular. Alguém tem alguma outra solução? Vou deixar os comandos com detalhes das especificações aqui pra facilitar a interpretação de vcs.inxi -Fxz
