[RÉSOLU] Perte du signal wifi depuis quelques jours

Bonjour,
J'ai installé ubuntu sur mon ordinateur Sony depuis la version 12.04. Je n'ai jamais eu de soucis de connexion jusqu'à présent. Suite à une mise à jour aux alentours du 20 décembre, le wifi ne fonctionne plus sur mon ordinateur. Il repère bien le nom de la livebox, tente de se connecter, puis s'arrête. Il refait ça en boucle, jusqu'à ce que je désactive avec l'interrupteur le wi-fi et passe en filaire.
Au moment de cette mise à jour j'ai constaté un autre bug: mon clavier est subitement devenu qwerty... Ce problème là s'est réglé tout seul (redémarrage suivant , c'était bon)
J'ai regardé les autres posts et la doc, mais je ne trouve pas ce qui ressemble à mon soucis et du coup j'ai peur de faire n'importe quoi...
Voici les résultats des lignes de commande demandées:

Re : [RÉSOLU] Perte du signal wifi depuis quelques jours

Bonjour,

ta livebox fait un cryptage "a probleme", connecte toi sur l'interface d'administration de ta livebox et passe le chiffrement wifi  soit qu'en wpa1 TKIP, soit qu'en WPA2 AES (ne pas oublier d'enregistrer les changement).
Coté ubuntu, déconnecte toi  - puis reconnecte toi, et test ton wifi

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] Perte du signal wifi depuis quelques jours

Merci pour ta réponse toutafai.
J'ai essayé les deux deux méthodes, mais cela ne fonctionne toujours pas. Je précise également que le wifi marche très bien sur mon téléphone android.

Re : [RÉSOLU] Perte du signal wifi depuis quelques jours

Bon j'ai réessayé plusieurs fois, j'ai rebooté ma livebox je ne sais combien de fois, mon ordi etc... bref, impossible... Quelqu'un aurait-il une autre solution à me proposer? Merci d'avance! (Peut-être que le problème vient de mon dual-boot et d'une connerie que j'ai pu faire sous windows? Je n'y vais quasiment jamais, mais peut-être j'ai pu faire une manip ou alors une maj automatique à fait foirer l'ensemble?)
Merci d'avance!

Re : [RÉSOLU] Perte du signal wifi depuis quelques jours

Salut,

As tu essayé ce qui est indiqué dans la doc de ta carte atheros AR9285 (§2.8 et §3) ? : http://doc.ubuntu-fr.org/wifi_atheros_ar9285.

dibadju

Re : [RÉSOLU] Perte du signal wifi depuis quelques jours

Merci Aix!
La manip du §2.8 a fonctionné. Tout du moins pour l'instant! Comme je ne sais pas pourquoi ça a planté au départ (je suis preneur d'une explication! ), je ne suis pas à l'abri que ça recommence... En tout cas, je te réponds en wi-fi!
Je place un résolu, en croisant les doigts pour que ça ne recommence pas!
