Bonjour à tous
Je suis sous Ubuntu 14.04 LTS que je mets à jour quotidiennement.
Ce matin j'effectue une petite MAJ via le gestionnaire de MAJ automatique. Je reboot et depuis mon ordinateur n'arrive plus à se connecter à ma box. Il voit la connexion et tente de s'y connecter mais n'y arrive pas. Pour information j'ai un second ordinateur qui lui arrive à s'y connecter...
Je peux me connecter à ma box uniquement en ethernet.
J'ai tenté de résoudre mon problème via le paragraphe 6.2 de la page
wifi car cela semblait correspondre à mon problème mais sans succès.
Du coup je sollicite votre aide pour m'aider à résoudre ce problème.
J'ai utilisé wificheck comme recommandé
ici. Voici le résultat :
