Bonjour, je viens d'installer Ubuntu 18.04 sur un vieux laptop et je n'arrive pas a allumer ma carte wifi.
Il n'y a pas de dualboot windows sur la machine.
La combinaison de touches Fn + F1 qui permet normalement d'activer la carte wifi ne semble pas fonctionner.
J'ai testé sudo rfkill unblock all mais ma carte wifi reste a "hard blocked : yes" après la manip.
J'ai parcouru pas mal de posts et vu que ca pouvait peut etre venir des modules mais je n'y comprends pas grand chose....
Ci dessous le resultat de wificheck, j'espère que quelqu'un pourra m'aider !
Merci d'avance
