Ma wifi n'apparait plus
Bonjour,
Suite à un problème de bluetooth, j'ai dû rentrer quelques commandes dans mon terminal. Le problème est que maintenant ma wifi n'apparait même plus sur la barre d'outil de mon ordinateur! Que faire ? La connexion filaire ne marche plus également !

Re : Ma wifi n'apparait plus
Bonjour,
En version 14.04, d'abord essayer la solution de Libellule19,
reprise dans le post # 21 de cette discussion : forum.ubuntu-fr.org/viewtopic.php?pid=21517510#p21517510
pour rétablir la connexion !
Conseils pour les nouveaux demandeurs et pas qu'eux
Important : Pensez à passer vos sujets en [Résolu] lorsque ceux-ci le sont, au début du titre en cliquant sur Modifier sous le premier message, et un bref récapitulatif de la solution à la fin de celui-ci. Merci. Membre de Linux-Azur
