[Résolu] Impossible de me connecter en Wi-fi
Bonjour, je suis nouveau ici, mais vu l'entraide qu'il y a ici, j'espère trouver des réponses à mes questions.
Voilà, j'ai récemment installer Kubuntu sur mon PC. Et après l'installation, tout fonctionnait à merveille. Le Wi-Fi était reconnu sans problème.
Cependant, depuis que j'ai branché mon ordinateur en filaire, je n'arrive plus à me connecter en Wi-Fi. Je détecte les réseaux sans problème mais à chaque fois que j'essaye de me connecter ça ne fonctionne pas...
Je suis donc assez embarrassé.
Voilà, voilà, j'attends avec impatience vos lumières. 
P.S. : Je ne suis pas certain de poster au bon endroit, veuillez me pardonner si ce n'est pas le cas. (Je me flagellerai pour me punir ! 
)

Re : [Résolu] Impossible de me connecter en Wi-fi
bonjour,
tu est bien au bon endroit sauf que....comme 90% tu ne lis pas ce qu'il y a marqué a l'écran ! Regarde sur la page configuration wifi de ce forum (la ou on est et la) : Il y a des message "épinglés" (=dont le sujet est précédé par un point d'exclamation rouge dans un rond) ; tu va trouver un message "A lire avant de poster !!" ou "Script : Récolte des info des a lire avant des poster" lit et fait ce qui est demandé dans un de ces 2 messages
Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).

Re : [Résolu] Impossible de me connecter en Wi-fi
Merci pour cette réponse.
Entre temps j'ai réinstaller mon OS et fait des mises à jour.
Il s’avérait qu'il manquait un pilote permettant à ma carte Wi-Fi de gérer le WPA ...
Voilà voilà. Merci encore.
