Problème de connexion wifi
Bonjour,
Depuis quelques jours, je n'arrive plus à me connecter à mon wifi avec mon PC Toshiba sur Ubuntu. Mon beau-frère ayant un PC sous Windows 7 se connecte normalement. J'ai essayé de voir avec la hotline de mon fournisseur d'accès qui visiblement ne maitrise pas du tout Ubuntu.
J'ai lancé la commande sudo lshw -c network
j'ai le résultat suivant :
* - network

J'ai par contre essayé la commande wificheck sans succès.
Résultat : wificheck : commande introuvable
Merci d'avance pour votre aide !

Re : Problème de connexion wifi
Merci moko138.
Par contre, j'ai 2 questions :
- Où télécharger une mise à jour de la distribution ?
- Est-ce que la nouvelle version va solutionner mon problème ?
Merci.

2) Quand il y a le feu dans la maison, je ne me demande pas si j'ai bien rangé le lait au frigo.
1) As-tu regardé la page d'accueil ?
