Bonjour et merci de votre aide
J'ai créé "wifiwheck" depuis un autre OS installé sur le même ordinateur. (Je pense que les réponses doivent être identiques - je rappelle qu'aucune connexion n'est active dans Kubuntu 17.04 - filaire ou wifi bien que le wifi soit indiqué comme actif et c onnecté)

Le fichier nm-tool n'existe pas.
Si le problème devient trop ardu, pensez-vous qu'une réinstallation complète depuis l'iso puisse régler le problème ? Il semblerait que d'autres utilisateurs aient eu les mêmes ennuis depuis une installation "propre".
Merci encore. Dans l'attente
