bonjour,
je n'arrive pas à me connecter en wifi et suis très novice quant à l'utilisation d'un terminal, voire des ordinateurs en général...
comme il est conseillé en tête de ce forum, je vais copier les réponses aux lignes de commandes du terminal mais avant je souhaite expliquer le contexte de mon problème :
je viens d'acheter un ordinateur d'occasion sans disque dur
j'ai remis mon disque dur sur lequel était déjà installé xubuntu. (auparavant installé sur un msi, où tout était ok, mais peut être, un ami avait configuré la machine, je ne peux plus le contacté pour lui demandé)
xubuntu a démarré directement ! je n'ai rien du faire, depuis le premier démarrage, tout fonctionne...excepté le wifi.
j'ai lu que le problème est récurrent avec les carte broadcom, mais malgré les recherches et plusieurs actions via le terminal, je n'arrive toujours pas à trouver la solution
merci à toute personne qui voudra bien se pencher sur mon problème!
j'ai internet via la connexion filaire peut donc facilement télécharger des paquets ou autre.

pour cette dernière commande, je n'ai réussi pas sortir et du fermer le terminal. ces connexions qui apparaissent étaient fonctionnelles lorsque mon disqur était sur un ordinateur de secours que j'ai utilisé encore hier.

Erreur : paramètre « list » non reconnu. Essayez plutôt --help.
j'espère que quelqu'un pourra trouver une solution.
