pas de wifi disponible sur portable toshiba satellite A210

blafo

Bonjour
J'ai acheté pour mon fils de 14 ans ce portable d'occas. Belle qualité. Il a souhaité enlever le vista d'origine et mettre ubuntu. Il a la version 14.04.5 A210 tty (?)

Reseau wifi est grisé
Le wifi est désactivé par un commutateur materiel. Grisé
Activer le reseau wifi. Grisé

Dans paramètres Réseau, Le semblant de bouton ne veut pas se mettre sur ce qui semble être ON

Dans "modification des connexions" J'aurais peut-être la possibilité de créer un réseau wifi mais là, je bloque, il y a des éléments qui me semblent difficile à appréhender.
Si vous aviez un élément de réponse, merci d'avance (j'ai cherché, pas trouvé)

pourquoi prendre la 14.04 alors que la 16.04 est lts aussi?
pouvez-vous essayer la nouvelle version?
visiblement la carte est détecte (atheros)
en recherchant sur 168c:001c qui est l'identifiant materiel de votre carte vous trouverez des infos dessus...
Un autre membre peut t'il aider?

une commande

dmesg

peut aider aussi a comprendre pourquoi il y a un soucis

et visiblement cette personne à la mème carte que vous : https://forum.ubuntu-fr.org/viewtopic.php?id=1428931

moko138 a écritEntre-temps, j'ai retrouvé ce message ./viewtopic.php?pid=21563767#p21563767 de toutafai (8/2016) :
Ta box utilise un double chiffrement (à la fois du wpa1 et du wpa2), c'est certainement la source de ton problème.
Connecte toi sur l'interface d'administration de ta box et change moi cela pour
soit que du wpa1 TKIP,
soit que du wpa2 AES
(ne pas oublier d'enregistrer les changements sur ta box),
Une fois que ce sera fait, tu ne devrais plus avoir de déconnexions

Bonsoir
Tout d'abord, j'ai migré vers la 16.04. Ensuite j'ai changé en wpa1 TKIP, rien. Essayé en WEP avec clé. Rien. Toujours rien. Désespérant.
Merci

Doc : [doc]wifi[/doc]

extrait § 4.1 a écritSi après Soft blocked vous avez un yes, alors le Wi-Fi est bloqué de façon logicielle, par contre si vous avez un yes après Hard blocked c'est que votre Wi-Fi est bloqué matériellement par un bouton dédié.

sur l'ordi,tu as un interrupteur ou une combinaison de touche pour activer ton wifi ?

blafo

Ha
Comme je le disais, c'est un portable d'occasion. Je vais chercher.
Merci

blafo

Bon, j'ai trouvé un commutateur physique sur le pc. Je(c'est quoi l'interêt d'un pareil bouton!) l'ai mis en On. J'ai pu créer mon reseau wifi, Cependant, même si ubuntu me dit que je suis connecté en wifi, je ne le suis pourtant pas. Je vais remettre les information
