Olá zekkerj,
Obrigado por disponibilizar o seu tempo para me ajudar
Fiz os comandos que vc sugeriu ( e alguns outros que vi em outro post que pode ser útil):
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

A rede que eu utilizo não apareceu. Tentei configurar manualmente (eu sei o SSID dela) mas não adiantou. Será que eu tenho que atualizar alguma coisa, como você sugeriu ? o que seria ?
Obrigado mais uma vez !
