Bonjour à tous,
J'ai tenté le passage de Kubuntu 14.04 au 16.04. J'ai eu plusieurs gros problèmes dont l'impossibilité d'utiliser le WIFI. Je suis passé sur ubuntu 14.04, mais je n'arrive toujours pas à utiliser le WIFI. Je tiens à préciser que cela fait deux jours que je tente des solutions en vain.
Avant tout je vous fournis les infos de mon wifi (obtenues avec wget -N -t 5 -T 10

Voici aussi le résultats de iwconfig:
lo no wireless extensions.
eth0 no wireless extensions.
J'ai essayé plein de trucs et je sais pas trop comment vous présenter tout ca alors n'hésitez pas à me poser des questions.
Merci par avance pour votre compassion, la je suis un peu désespéré je vous avoue.
Minoob le gros noob
Solution trouvée: Le pb étant du à une migration, je l'ai solvé en réinstallant ubuntu sur la meme partition sans la formater ( voir procédure dédiée à la réinstallation sur ce site).
