Mon problème se rapproche fortement de ce topic, mais la résolution ne fonctionne pas pour moi.
Mon problème est le suivant : j'arrive à me connecter sur mon réseau wifi, j'ai même pu l'utiliser un certain temps, jusqu'à ce que ça coupe. Depuis, rien à faire, la connexion "physique" se fait, mais aucune communication. Je ne peux rien pinger, même pas le routeur. Tous les autres périphériques du réseau fonctionnent.
Voici ce que donnent les différents commandes de diagnostic :
