désactivation wifi non souhaitée
Bonjour
Sur un Sony Vaio, avec Ubuntu 12.04, le Wifi marche bien, mais je rencontre le souci suivant qui fait perdre pas mal de temps :
Si je démarre dans une zone où il n'y a pas de Wifi ou bien aussi après avoir décoché volontairement "Activer le réseau sans fil"
Quand je rédémarre avec des réseaux à portée, et sans avoir touché au bouton matériel, je vois : "Réseau Wifi désactivé par un connecteur matériel"
Bien sûr, impossible de me connecter alors.
Je redémarre sous Windows : le Wifi marche parfaitement.
Je redémarre sous Linux : Toujours pas de Wifi, même situation que ci-dessus.
Pour me débloquer, la seule solution trouvée pour l'instant (chaque action est indispensable) :
1) Faire :
sudo rfkill unblock all2) Démarrer sous Windows, sans rien faire de particulier
3) Redémarrer sous Ubuntu, activer le réseau sans fil, et là tout va bien...
Mais ça me parait un peu compliqué...et puis comment font les gens qui n'ont pas Windows en dual boot ?
Est-ce que ce problème est connu et est-ce qu'il existe une solution ?
Merci

Re : désactivation wifi non souhaitée
Bonjour,
le fautif n'est pas ubuntu. Le probleme vient soit du bios qui n'active/ne force pas le wifi à etre actif dès la mise sous tension du portable (a vérifier), soit de windows (et du pilote wifi ou de son gestionnaire) qui désactive le wifi lors de l'arrete de windows (à vérifier aussi)...
Sony est aussi "spécialiste" pour avoir une gestion d'energie "agressive" et qui peut donc désactivé le wifi, c'est toujours dans le bios que cela se passe quand les options sont disponible).verifier tous ces points !
Ps : les gens qui n'ont pas windows n'ont pas ce probleme (a part pour le bios sur certain modeles)
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 ^^^).
